grin007 [14]

Answer:

Step-by-step explanation:

First, turn the word problem into an equation:

n(a number) was divided by 2

$\frac{n}{2}$

followed by this quotient beying multiplied by 4

$\frac{n}{2}$ *4

the product was added to 9

$\frac{n}{2}$ *4+9

the total sum was 25

$\frac{n}{2}$ *4+9 = 25

use PEMDAS to solve the equation

subtract 9 on both sides

$\frac{n}{2}$ *4 = 16

cancel the 2 and the 4 using factorization

n*2 = 16

divide 2 on both sides

n = 8

Find a value for b so that the polynomial x^2+ bx + 25 factors to (x + 5)^2.

Marta_Voda [28]

Answer:

10 = b

Step-by-step explanation:

Begin by expanding (x + 5)^2

(x + 5)(x + 5)

First: x*x = x^2

Outside: x * 5 (the last term which is a 5)

Inside: 5+ x

Last: 5*5 = 25

x^2 + 5x + 5x + 25

x^3 + 10x + 25
