As we know :

  • \boxed{ \boxed{ {(a + b)}^{3}  =  {a}^{3} +  {b}^{3} + 3ab(a + b)  }}

now let's plug the value of given terms :

  • (5)³ = a³ + b³ + (3×3)(5)

  • 125 = a³ + b³ + 45

  • a³ + b³ = 125 - 45

  • a³ + b³ = 80

Find EF if EM= x^2+25 and MF = 10x
N76 [4]

Answer:

x^2 + 10x + 25; (x + 5)^2.

Step-by-step explanation:

When we're talking about line segments, we just have to find the sum of the two parts of the line segment to find the value of the whole. In this case, we have x^2 + 25, and 10x. So, we add them together.

x^2 + 25 + 10x

= x^2 + 10x + 25

Since this can be immediately factored into (x + 5)^2, you have your answer.

Hope this helps!

Solve using Combining Like Terms (CLT)<br><br> 7 + 4d + 5d = 7d + 3
Vesnalui [34]

Answer:

d= -2

Step-by-step explanation:

7 + 4d + 5d = 7d + 3

Combine like terms

7+9d = 7d+3

Subtract 7d from each side

7+9d-7d = 7d-7d+3

2d +7 = 3

Subtract 7 from each side

2d+7-7 = 3-7

2d = -4

Divide each side by 2

2d/2 = -4/2

d = -2
