Answer:

Step-by-step explanation:

AC² = AD² + DB ²

25 = AD² + 9

AD² = 16

AD = 4

Area = 4*3 /2

Can someone please help me with # 2 #13 thanks show work how it's done, please
zavuch27 [327]

Problem 13

10p+10q factors to 10(p+q). If we apply the distributive property, we can distribute the 10 to each term inside (p and q) to get

10(p+q) = (10 times p)+(10 times q) = 10*p + 10*q = 10p+10q

so we get the original expression again. Here 10 is the GCF of the two terms.

--------------------------------------------------------------

Plug p = 1 and q = 2 into the factored form

10*(p+q) = 10*(1+2) = 10*(3) = 30

As a check, let's plug those p,q values into the original expression

10*p+10*q = 10*1+10*2 = 10+20 = 30

We get the same output of 30

Answer:

535

Step-by-step explanation:

8 x 7 = 56

15 x 17 = 255 .  255 / 2 = 127.5

15 x 17 = 255 .  255 / 2 = 127.5

15 x 7 = 105

17 x 7 = 119

119 + 105 + 127.5 + 127.5 + 56 = 535
