Lets first convert everything to inches.
6 feet= 12*6 = 72 + 10 = 82 inches
8 feet= 12*8 = 96+9 = 105 inches
Now add!
82+105 = 187
Now convert them back to feet.
187/12 = 15 feet
12*15 = 180
187 - 180 = 7 inches
15 feet. 7 inches.
Final answer: B. 15 ft. 7 in.
Answer:
2
- 5x² - 63
Step-by-step explanation:
Given
(2x² + 9)(x² - 7)
Each term in the second factor is multiplied by each term in the first factor, that is
2x² (x² - 7) + 9(x² - 7) ← distribute both parenthesis
= 2
- 14x² + 9x² - 63 ← collect like terms
= 2
- 5x² - 63
Replace b with 7 in the binomial and simplify.
b + 16
Let b = 7
7 + 16 = 23
It'll be -25... when u subtract -20 with 5 the answer will be -25
work:
(-20-5= -25)
