Step-by-step explanation:

Problem #1:

1. Find the GCF (Greatest Common Factor)

$GCF = 2$

2. Factor out the GCF and simplify.

$2(x^{2} +7x+10)$

3. Factor $x^{2} +7x+10$

Which two numbers add up to 7 and multiply to 10?

2 and 5

Rewrite the expression using the above.

$(x+2)(x+5)$

4. Done!

$2(x+2)(x+5)$

Problem #2:

1. Find the GCF (Greatest Common Factor)

$GCF=8$

2. Factor out the GCF and simplify.

$8(x^{2} +8x+16)$

3. Use the perfect square formula. $a^{2} +2ab+b^{2} =(a+b)^{2}$

$a = x\\b=4$

$(x+4)^{2}$

4. Done!

HELP PLEASE GEOMETRY find x and y

dimulka [17.4K]

$3x + 30 + 2x - 20 = 360 \\ 5x + 10 = 360 \\ 5x = 350 \\ x = 70$
$y = \frac{3x + 30 - 2x + 20}{2} = \frac{x + 50}{2} = \frac{120}{2} = 60$
