Answer:

The correct answer is D. (15 + 5) /10

Step-by-step explanation:

Let's resolve the question, this way:

The sum of 15 and 5, divided by 10.

The sum of 15 and 5 = 15 + 5, but like the result of this addition will l be divided by another number, we should use the parenthesis.

So, we have (15 + 5)/10 because the sum of 15 and 5 is divided by 10 not just the second term, in this case 5.

The correct answer is D. (15 + 5) /10

-2(8p+2)-3(2-7p)-2(4+2p)=0

zysi [14]

-2(8p+2)-3(2-7p)-2(4+2p)=0

mutiply the first bracket by -2

(-2)(8p)= -16p

(-2)(+2)= -4

mutiply the second bracket by -3

(-3)(2)= -6

(-3)(-7p)= 21p

mutiply the third bracket by -2

(-2)(4)= -8

(-2)(+2p)= -4p

-16p-4-6+21p-8-4p= 0

-16p+21p-4p-4-6-8= 0 ( combine like terms)

5p-4p-4-6-8= 0

p-4-6-8= 0

p-10-8= 0

p-18= 0

move -18 to the other side to get p by itself

sign changes from -18 to +18

p-18+18= 0+18

p= 0+18

Answer: p= 18

I need help with this problem down below

Misha Larkins [42]

Answer:

$y = 4$

Step-by-step explanation:

Given:

$y = \frac{7x + 1}{3x - 6}$ ,

To find the value of y, let's find x by solving 3x = 15.

3x = 15

Divide both sides by 3

x = 15/3

x = 5

Plug in the value of x into $y = \frac{7x + 1}{3x - 6}$

$y = \frac{7(5) + 1}{3(5) - 6}$

$y = \frac{35 + 1}{15 - 6}$

$y = \frac{36}{9}$

$y = 4$

Solve for W: P=2L + 2W A. W=P-L B. W= 1/2P - L C. W= 1/2 P + L D. W= 2P - L

svetlana [45]

Answer:

Step-by-step explanation:

$P=2L+2W$

$P-2L=2W$ (Subtract 2L from both sides of the equation)

$2W=P-2L$ (Symmetric Property of Equality)

$W=\frac{P-2L}{2}$ (Divide both sides of the equation by 2)

$W=\frac{P}{2} -\frac{2L}{2}$ ("Split" the fractions)

$W=\frac{1}{2}P-L$ (Simplify)

Hope this helps!

A rectangle has a height of 4x ^ 3 width of x ^ 3 + 3x ^ 2 + 2x . Express the area of the entire rectangle .

astra-53 [7]

Answer:

$4x^6+12x^5+8x^4$

Step-by-step explanation:

To find the area of a triangle, you need to multiply the width by the height. In this case:

$(4x^3)(x^3+3x^2+2x)=\\4x^6+12x^5+8x^4$

Hope this helps!
