Step-by-step explanation:
The equivalent expression of [tex](a^{-2}.8^{7} )^{2}[/tex] is [tex]a^{-4} .8^{14}[/tex].
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:
Constant: A constant is a fixed numerical value.
Variable: A variable is a symbol that doesn't have a fixed value.
Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.
Coefficient: A coefficient is a number that is multiplied by a variable in an expression.
Given expression
[tex](a^{-2}.8^{7} )^{2}[/tex]
Using formula [tex]a^{-m} =\frac{1}{a^{m} }[/tex]
= [tex](\frac{8^{7} }{a^{2} } )^{2}[/tex]
= [tex]\frac{(8^{7}) ^{2} }{(a^{2}) ^{2}}[/tex]
Using [tex](a^{m} )^{n} =a^{m \times n}[/tex]
= [tex]\frac{8^{14} }{a^{4} }[/tex]
= [tex]a^{-4} .8^{14}[/tex]
Option C is correct.
The equivalent expression of [tex](a^{-2}.8^{7} )^{2}[/tex] is [tex]a^{-4} .8^{14}[/tex].

what is the value of x?
Answer:
probs too late, but i think the answer is x=12
Step-by-step explanation:
the angles should add up to equal 180
180-36=144
144=8x+4x
144=12x
now divide by both sides to isolate x
12=x
u can check by plugging in ofc, 36+(8x12)+(4x12)=36+96+48=180
:) hope this helps

Answer:
A: SSS | B: HL | C: SAS
Step-by-step explanation:
Firstly, SSS is where you know that each side of a triangle is congruent to the other triangle.
Secondly, SAS is where you know two sides and an angle are congruent. This angle will be between two sides that are congruent. This can be put clockwise or counterclockwise, but the sides and angle must be consecutive.
Thirdly, AAS is where you know two angles and one side are congruent.
Lastly, HL (Theorem) is where you know that the hypotenuse and a leg of a right triangle are congruent.
A: TU≅WX, ST≅XV, and SU≅VW
B: Two right triangles; HA and OK are the hypotenuses, and HA≅OK, RH≅RK
C: ZW≅YX, ∠W≅∠X, and WX≅WX

Which linear equations have one solution? Check all that apply.
5x - 1 = 3(x + 11)
4(x - 2) + 4x = 8(x – 9)
4(x – 6) + 4 = 2(x - 3)
2(x – 4) = 5(x – 3) + 3
2(x - 1) + 3x = 5(x - 2) + 3
Step-by-step explanation:
linear equations have one solution are:-
5x - 1 = 3(x + 11)
4(x – 6) + 4 = 2(x - 3)
2(x – 4) = 5(x – 3) + 3
Answer:
The linear equations that have one solution are:
5x - 1 = 3(x + 11)
4(x – 6) + 4 = 2(x - 3)
2(x – 4) = 5(x – 3) + 3

Answers:
Sam's current age = 24The mother's current age = 48=========================================================
Explanation:
s = Sam's age right now
2s = the mother's age right now, since she is twice as old as Sam currently.
In 12 years time, Sam will be s+12 years old.
12 years ago from this current year, the mother was 2s-12 years old.
Since we're told these future and past ages line up, this means s+12 and 2s-12 are the same value
Set the expressions equal to one another and solve for s.
s+12 = 2s-12
s-2s = -12-12
-s = -24
s = 24
Sam is currently 24 years old.
His mother is currently 2s = 2*24 = 48 years old.
12 years ago, his mother was 2s-12 = 48-12 = 36 years old.
12 years from now, Sam will be s+12 = 24+12 = 36 years old.
Since we get 36 each time, this confirms we have the correct answers.

Subtract
273,054
- 184,095
Answer:
88,959
Step-by-step explanation:
it's subtraction. I got the answer
Answer:
88,959
Step-by-step explanation:
Clearly, we do the ones place first, and so..
054

095 =
We borrow from 5 which turns into 4 and 4 turns into 14.
14 - 5 = 9
So our first number is 9!
= __9
We borrow from the thousands, 3 becomes 2 and 0 becomes 10!
We can't subtract 4 from 9 so we borrow from 10, 10 becomes 9 and 4 becomes 14.
14 - 9 = 5
( Now i'm getting lazy so I will just show the steps without as many words )
9 - 0 = 9
~~~~~~~~~~~~~~~
054 - 095 = 959
! Hundreds place !
( 3 is now a 2 since we borrowed from 3)
272
-
184 =
( Borrowed from 7 to make 12 so 7 is now 6 )
12 - 4 = 8
~~~~~~~~~~~~~~~
(We need to borrow from the first 2 in 272 to make 16 from when we borrowed from 7 )
16 - 8 = 8
~~~~~~~~~~~~~~~
(2 was borrowed so it's now 1 )
1 - 1 = 0
~~~~~~~~~~
And we get 088,959
Remove the 0 and we have 88,959
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I hope this helps you!

Find all sides of a right triangle whose perimeter is equal to 60 cm and its area is equal to 150 square cm
Answer:
15cm by 20cm by 25cm
Step-by-step explanation:
Let the sides of the right angle be x, y and h
x is the breadth
y is the height
h is the hypotenuse
Perimeter = x + y + h
x + y +h = 60
x+y = 60-h .... 1
If its area is equal to 150 square cm, then;
Area = 1/2 * base * height
Area = 1/2 *x * y
xy/2 = 150
xy = 300 ....2
According to pythagoras theorem;
x² + y² = h²
On expanding x² + y²
x² + y² = (x+y)² - 2xy
The equation becomes
(x+y)² - 2xy = h² ... 3
Substitute equation 1 and 2 into 3;
From 3;
(x+y)² - 2xy = h² ... 3
(60-h)² - 2(300) = h²
3600-120h + h² - 600 = h²
3600-120h - 600 = 0
-120h = 600-3600
-120h = -3000
h = 3000/120
h = 25cm
Recall that x+y+h = 60
x+y+25 = 60
x+y = 60 - 25
x+y = 35 ... 4
From equation 2;
xy = 300
x = 300/y ..... 5
Substitute 5 into 4;
300/y + y = 35
(300+y²)/y = 35
300+y² = 35y
y²-35y + 300 = 0
y²-20y-15y + 300 = 0
y(y-20)-15(y-20) = 0
y-20 = 0 and y - 15 =0
y = 20 and 15
since x+y = 35
x + 20 = 35
x = 35 - 20
x = 15
Hence the sides of the triangle are 15cm by 20cm by 25cm

Missy uses 1 hexagonal, 3 rectangular, and 4 triangular pieces of fabric to make 1 bug design for a quilt. If she uses 80 pieces in all to make bug designs, how many of each shape does she use?
Answer:10 hexagonal, 30 rectangular and 40 triangular pieces of fabrics
Step-by-step explanation:
This question is a ratio/proportion question
The ratio of hexagonal pieces use to rectangular pieces used and to triangular pieces used can be expressed as 1:3:4
Total pieces of fabrics used = 80
Total ratio = 1 + 3 + 4 = 8
We can calculate each ratio as a proportion of the total ratio
pieces of hexagonal used = (1/8) * 80 =10
Pieces of rectangular used = (3/8) * 80 =30
Pieces of triangular used = (4/8) * 80 = 40
And hence the pieces of each shapes used will be 10 hexagonal, 30 rectangular and 40 triangular pieces of fabrics
And the total number of bugs designs made = (80/8) = 10 (since it will require 8 pieces of fabrics(1 + 3 +4) to make a bug design)
