Answer:
D
Step-by-step explanation:
Given
- 4(x - 6) + 3(a - 7)
distribute the first parenthesis by - 4 and the second by 3
= - 4x + 24 + 3a - 21
= - 4x + 3a + 3 → D
Use c^2=a^2+b^2
26^2= 13^2 + b^2
676=169 + b^2 (subtract 169 from both sides)
507= b^2 (take the square root of each side)
22.52 in. =b
