Answer:

6(3 + 2)

Step-by-step explanation:

You can find the GCF by finding their prime factorization.

18 = 3×3×2

12 = 3×2×2

they both have 3×2 in common which is 6

so 6(3) is 18 and 6(2) is 12 you will get 6(3 + 2).

I hope this helps,

Answer:

11. $500z^{2} +400z+80$

12. $704a^2 + 1344a + 640$

13. $160y^2 + 44zy^2 + z^2y^2$

Step-by-step explanation:

11. $(50z + 20)(10z + 4) = ?$

Using Formula:

$(a+b) (c+d) = a(c+d)+b(c+d)$

$50z(10z+4) + 20(10z + 4) = \\\Rightarrow 500z^{2} + 200 z+200z+80\\\Rightarrow 500z^{2} +400z+80$

12. $(88a + 80)(8a + 8) = ?$

Using Formula:

$(a+b) (c+d) = a(c+d)+b(c+d)$

$\Rightarrow 88a(8a+8) + 80(8a + 8)\\\Rightarrow 704a^2 + 704a + 640a + 640\\\Rightarrow 704a^2 + 1344a + 640$

13. $(40y + zy)(4y + zy) = ?$

Using Formula:

$(a+b) (c+d) = a(c+d)+b(c+d)$

$\Rightarrow 40y(4y + zy) + zy(4y + zy)\\\Rightarrow 160y^2 + 40zy^2 + 4y^2z + z^2y^2\\\Rightarrow 160y^2 + 44zy^2 + z^2y^2\\$

Find the measure of ∠b.

luda_lava [24]

Answer:

B. 38°

Step-by-step explanation:

The angles of a triangle add up to 180.

So, 62 + 80 + b will add up to 180.

First, we add 62 =80, which gives us 142.

The we subtract 142 from 180, which gives us 38.
