Answer:
ITS A (i took the unit test)
Step-by-step explanation:
Select all statements that are true about the triangles.
Answer:
D and E
Step-by-step explanation:
D) Δ ABC , ΔDCB
AB = DC
BC = CB
AC = DB
Side Side Side congruent.
E)Δ ABC , ΔDCB
AB = DC
∠D = ∠A
AC = DB
Side Angle Side congruent.
Answer:
E
Step-by-step explanation:
When we write that 2 triangles are congruent we have to write the letters in order of their corresponding sides so ΔABC has the sides in order
AB, then BC, and then CA
the corresponding sides of the other triangle are
DC, then CB, then BD so the other triangle should be Δ DCB
because (AB≅DC, BC≅CB, CA≅BD)
In this case we eliminate the A,B,C answers.
D is also not correct because we do not know if <ABC is congruent with <DCB
E is correct because we are given the sides AB≅DC, and CA≅BD and we know that BC≅CB because of the reflexive property (a line segment is congruent with itself).
We have 3 ≅sides so we can use the Side-Side-Side Congruence Theorem
F is not correct because we have enough information.

what is 26 divide 7,124
Answer:
1/274
Step-by-step explanation:
Solution 1: Use a fraction simplifier calculator :)
Solution 2: divide by 2 first, then test to find 13, and your there.
Answer: There are two answers ( just for explanation ) 1. 0.0036496350364964 2. 274
Step-by-step explanation:
1. If we do 26 divided by 7124 answer is = 0.0036496350364964 ( check the pic-div1, div2, div3 )
2. If we do 7124 divided by 26 answer is = 274 (check pics-div4, div5)
6. Write the following cubes in expanded form:
(iii) (3a + 4b)³
8. Evaluate the following cubes using suitable Identities:
(ii) (999)³
Answer:
Step-by-step explanation:
we can use this algebraic identity:
[tex](a+b)^{3} =a^{3} +b^{3} +3ab(a+b)[/tex]
So,[tex](3a+4b)^{3} =(3a)^{3} +(4b)^{3}+3(3a)(4b)(3a+4b)[/tex]
=[tex](3a+4b)^{3} =27a^{3} +64b^{3} +36ab(3a+4b)[/tex]
=[tex](3a+4b)^{3} =27a^{3} +64b^{3} +108a^{2} b+144ab^{2}[/tex]
[tex](999)^{3}[/tex]=[tex](1000-1)^{3}[/tex]
Now, we can use the following identity:
[tex](a-b)^{3} =a^{3} -b^{3} -3ab(a-b)[/tex]
=[tex](1000-1)^{3} =1000^{3} -1^{3} -3(1000)(1)(1000-1)\\[/tex]
[tex](1000-1)^{3} =1,000,000,000-1-2,997,000[/tex]
[tex](1000-1)^{3} =997,002,999[/tex]

Step-by-step explanation:
25x^2-15x+25
=5(5x^2-3x+5)
b.
14xy-7x
=7x(2y-1)
5.a.
7x-4=24
or,7x=24+4
or,7x=28
or,x=28/7
therefore x=4
b.
4y+4=y+16
or,4y-y=16-4
or,3y=12
or,y=12/3
therefore y=4
Step-by-step explanation:
q 5)
a) as it's an Isosceles triangle so both the given sides are equal
so, a/q
→ 7x - 4 = 24
→ 7x = 24 + 4 = 28
→ x = 28/7 = 4
→ x = 4
therefore, value of x is 4.
b) 4y + 4 = y + 16
→ 4y - y = 16 - 4
→ 3y = 12
→ y = 12/3 = 4
→ y = 4
therefore, value of y is 4.

C. 1. 2009
D. 2. 7009
Answer:
C. 1.2009
Step-by-step explanation:
1.3240 + 1.4872 = 2.8112
4.0121 - 2.8112 = 1.2009 - C

2) translation: 2 units up
Q(-4,-2), R(-4,-2), s(0, -2), t(-3-5)
Answer:
Q'(-4,0), R'(-4,1), S'(0,0), T'(-3,-3)
Step-by-step explanation:
To solve this, what we need to do is find out what the translation is. So if we are translating those coordinates up two units, then that means we are basically adding two to the y value.
So that means that we will use the mapping (x,y)→(x,y+2)
Now we plug this in. We will start with Q:
Q(-4,-2)→Q'(-4,-2+2)→Q'(-4,0)
So when Q is translated two units up, we get Q'(-4,0).
Now we will do R:
R(-4,-1)→R'(-4,-1+2)→R'(-4,1)
So when R is translated two units up, we get R'(-4,1).
Now we will do S:
S(0,-2)→S'(0,-2+2)→S'(0,0)
So when S is translated two units up, we get S'(0,0).
Next we will do T:
T(-3,-5)→T'(-3,-5+2)→T'(-3,-3)
So when T is translated two units up, we get T'(-3,-3).

What is the slope of the following line?
A. 1/3
B. - 1/3
C. 3
D. - 3
Answer:
A
Step-by-step explanation:
Points of origin are (-3,0) and (0,1). Now we determine if it is a positive slope, it is as it goes up not down. It goes up 1 unit and over to the right 3 units, making the slope 1/3.

C. 58x + 8
d. 14x - 125
Please select the best answer from the choices provided
Ο Α
OB
Answer:
B
Step-by-step explanation:
Perimeter is the sum of all the lengths of its sides.
Perimeter of the figure
= 9x +8x -2 +17x -6 +5x +1
= 9x +8x +17x +5x -2 -6 +1
= 39x -7
Thus, the correct answer is option B.
the difference of complementary angles is 10 degree. find the measures of the angles.
Answer:
40° and 50°
Step-by-step explanation:
90=(x+10)+x
90=2x+10
80=2x
40=x
Therefore the answer is,
40 and 40+10
40° and 50°
Answer:
50° and 40°
Step-by-step explanation:
Complementary angles sum to 90°
let one angle be x then the other is x - 10
x + x - 10 = 90
2x - 10 = 90 ( add 10 to both sides )
2x = 100 ( divide both sides by 2 )
x = 50
x - 10 = 50 - 10 = 40
The angle measures are 50° and 40°

9b-27= 3(2b-8)+2b solve for b
please show work on how you found b
Answer: b = 3
Step-by-step explanation:
9 − 27 = 3(2 − 8) + 2
9 − 27 = 6 − 24 + 2
9 − 27 = 6 − 24+ 2
9 − 27 = 8 − 24
9−27=8−24
9−27+27=8−24+27
9 = 8 + 3 ------Subtract 8b from both sides
b = 3
