Answer:
10. The base of the rectangle is 3 inches
11. The tree was 21 meters tall
Step-by-step explanation:
10. 42 / 14 = 3
11. 7 x 3 = 21
Answer:
a) x-intercepts are (0,0) and (5,0)
b) 6.25 yards
Step-by-step explanation:
a) x intercepts are:
-x² + 5x = 0
-x(x - 5) = 0
x = 0, 5
b) -x² + 5x
-(x² - 5x)
-[x² - 2(x)(5/2) + (5/2)² - (5/2)²]
-(x - 5/2)² + 25/4
Max height is:
25/4 yards or 6.25 yards
Answer:
(x^2+4)(x-2)
Step-by-step explanation:
We can factor by grouping
take out x^2 from the first two terms, and factor out 4 from last two terms
x^2(x-2)+4(x-2)
(x^2+4)(x-2)
Answer:
This is so easy.
