Solve: (11d+4)(9d+7)=0

Step-by-step explanation:

Set each factor, one by one, equal to 0, and solve each of the resulting equations:

11d + 4 = 0 becomes 11d = -4, or d = -4/11

9d + 7 = 0 becomes 9d = -7, or d = -7/9

3=log(n)=2

answer a: product property

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
