Option C is correct, 15a⁵b¹⁵ is the product of expression (3a²b⁷)(5a³b⁸)
We have to find the product of (3a²b⁷)(5a³b⁸)
a and b are the variables in the expression.
We have to find the product.
Let us first multiply the constant terms which are 3 and 5 we get 15
15 (a²b⁷)(a³b⁸)
We know that in a product if the bases are same then the powers will be added
15a⁵b¹⁵
Hence, option C is correct, 15a⁵b¹⁵ is the product of expression (3a²b⁷)(5a³b⁸)

PLEASE HELP ILL GIVE U BRAINLIEST (IGNORE WHERE IT SAYS 8 AND 2 POINTS BECAUSE THATS HOW MUCH ITS WORTH IN THE GRADEBOOK)
Answer:
x = 1, XZ = 48
Step-by-step explanation:
So you already have the diagram with the number labeled,
4(x + 5) and 2(x + 11)
We know that Y is the midpoint between X and Z so we know that XY = YZ:
4(x + 5) = 2(x + 11)
Let's solve the equation for x:
4x + 20 = 2x + 22 (Distributive Property)
Subtract 20 from both sides:
4x = 2x + 2
Subtract 2x from both sides:
2x = 2
Divide both sides by 2:
x = 1
So now we know that x = 1, we want to find XZ:
XZ = 4(x + 5) + 2(x + 11)
We can plug in x (1):
XZ = 4(1 + 5) + 2(1 + 11)
Simplify:
XZ = 4(6) + 2(12)
XZ = 24 + 24
XZ = 48
if (8^9)^p=8^18what is the value of p
Answer:
[tex]\huge\boxed{p=2}[/tex]
Step-by-step explanation:
In order to simplify this equation [tex](8^9)^p = 8^{18}[/tex], we have to use basic exponent rules.
Exponent rules tell us that [tex](a^b)^c = a^{b\cdot c}[/tex].
We have [tex](8^9)^p[/tex], so this means that it's equivalent to [tex]8^{9 \cdot p}[/tex] or just [tex]8^{9p}[/tex].
Now, we have [tex]8^{9p}=8^{18}[/tex]
Let's just focus on the exponents for now.
Since we know that in order for [tex]8^{9p}[/tex] to be equivalent to [tex]8^{18}[/tex], the exponents must be the exact same. So, [tex]9p=18[/tex].
We can find p by divide both sides by 9.
[tex]p = 2[/tex]

Which equation describes the line whose x-intercept is (4,0) and whose y-intercept is (0,-3)?
Answer:
[tex]y = \frac{3}{4}x - 3[/tex]
Step-by-step explanation:
In slope intercept form y = mx + b
We have the y intercept already so our equation becomes y = mx -3. Now we need to figure out the slope, we do this by subtracting the y values from both points and the x values from both points:
-3 - 0 = -3
0 - 4 = -4
Slope = -3/-4 the negatives cancel and now we have 3/4 as the slope.
Now the equation is y = 3/4x -3
[tex] y \: = \: \frac{3}{4} x \: - 3[/tex]
Double checking by inputting values such as x = 0 we now get (0, -3) which is correct and if the x-intercept is 4 then it should give us a y value of 0 which = (4,0). Yep! This is the correct linear equation for the line described

3x +21 6x-60 find the value of x 25 26 27 28 will.mark brainest
Answer:
Heloo
Step-by-step explanation:
Simplifying
3x + 21 = 6x + -60
Reorder the terms:
21 + 3x = 6x + -60
Reorder the terms:
21 + 3x = -60 + 6x
Solving
21 + 3x = -60 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
21 + 3x + -6x = -60 + 6x + -6x
Combine like terms: 3x + -6x = -3x
21 + -3x = -60 + 6x + -6x
Combine like terms: 6x + -6x = 0
21 + -3x = -60 + 0
21 + -3x = -60
Add '-21' to each side of the equation.
21 + -21 + -3x = -60 + -21
Combine like terms: 21 + -21 = 0
0 + -3x = -60 + -21
-3x = -60 + -21
Combine like terms: -60 + -21 = -81
-3x = -81
Divide each side by '-3'.
x = 27
Simplifying
x = 27
Answer:
x = 27Step-by-step explanation:
3x + 21 = 6x - 60
3x - 6x = -60 - 21
-3x = -81
x = 27
Which expressions are equivalent to 18 + 24?
Select all that apply.

3(6 + 21)
C
6(12 + 2)
D
6(3+4)
2(16 + 22)
OF
2(9 + 12)
Answer: A and D are correct because they both equal 42.
Step-by-step explanation: Both A and D when distributed equal 18 + 24.
B is incorrect because that equals 18 + 63
C is incorrect because that equals 72 + 12
The last one is incorrect because when simplified it is 76 of 30 and 76 of 30 equals 22.8, not 42.
Answer:
A only
Step-by-step explanation:
Not sure if your missing letter options. If D is asking all 3 to be right, then no, D is not correct. If there are 2 letters missing then the last equation also works.
I reread the question and option D seems like it is
6(3+4) * 2(16 + 22)
2(9 + 12)
Which equals
(42 * 76) / 42 = 72
So not D

5. Mr. Crossley is building a new dog house for Chester.
He starts with a piece of wood that is 8 feet long. How
many pieces of woods can he cut if he needs each piece
to be 2 feet?
Answer:
4 Pieces
Step-by-step explanation:
8 ÷ 2 = 4
Answer:
Step-by-step explanation:
Hello there!
He has 8 ft of wood, and he needs each peice to be 2 ft long. To solve this, we divide 8 ft by 2 ft (this will determine how many 2 ft peices can be cut from 8 ft). 8 ÷ 2 = 4, so this means he can cut four peices of wood to build the doghouse for Chester!

solve -5(x-7)^2+30=-20
Answer:
x=7−√10 or x=7+√10
Step-by-step explanation:
−5(x−7)2+30=−20
Step 1: Simplify both sides of the equation.
−5x2+70x−215=−20
Step 2: Subtract -20 from both sides.
−5x2+70x−215−(−20)=−20−(−20)
−5x2+70x−195=0
For this equation: a=-5, b=70, c=-195
−5x2+70x+−195=0
Step 3: Use quadratic formula with a=-5, b=70, c=-195.
x=
−b±√b2−4ac
2a
x=
−(70)±√(70)2−4(−5)(−195)

The perimeter of a triangle is 60 feet. If the sides are in the ratio 3:4:5, find the
length of each side.
Answer:
15,20,25
Step-by-step explanation:
The ratio of the sides is 3:4:5
So 3x + 4x + 5x = 60
12x = 60
x = 60/12
x = 5
The sides are therefore
3x = 3*5 = 15
4x = 4*5 = 20
5x = 5*4 = 25
Total 60 just what it should be
Choose the correct simplification of (7x^3y^3)^2. (5 points) 100 POINTS GIVING BRAINLIEST FOR GOOD EXPLANATION
Select one:
a. 14x^6y^6
b. 49x^5y^5
c. 49x^6y^6
d. 14x^5y^5
Answer:
Option C
Step-by-step explanation:
(7x^3y^3)^2
= (7)^2 * (x^3)^2 * (y^3)^2
= 49 * x^(3*2) * y^(3*2)
= 49x^6y^6
You have to distribute the terms in "7x^3 * y^3" each to the power of 2
(7)^2 * (x^3)^2 * (y^3)^2
Now you can apply the rule "(x^a)^b = x^a*b" and further simplify the expression
Answer:
it is c
Step-by-step explanation:
2x7=49 so its not a or d. 3x2=6 so both would be six so it is 49x^6y^6
