Step- Theby-step explanation:The answer is 21/2
This is the step:
(x-8)/5=2/4,then you can get (x-8)=(2/4) multiply by 5
(x-8)=10/4=5/2
x=(5/2)+8
x=21/2
Answer:
<h2><u><em>
6 feet</em></u></h2>
Step-by-step explanation:
Find the height of a square pyramid that has a volume of 8 cubic feet and a base length of 2 feet
Volume v = 1/3*a²h
inverse formula
8 = 1/3 * 2² * h
8 = 4 h /3
divide both the sides by 4
<u><em>h = 6 feet</em></u>
Answer:
f(-4) = 72, f(x + 5) = 3x² + 23x + 36
Step-by-step explanation:
f(-4) = 3(-4)² - 7(-4) - 4
= 48 - (-28) - 4
f(-4) = 72
f(x + 5) = 3(x + 5)² - 7(x + 5) - 4
= 3(x + 5)(x + 5) - 7(x + 5) - 4
= 3(x² + 10x + 25) - 7(x + 5) - 4
= 3x² + 30x + 75 - 7x - 35 - 4
f(x + 5) = 3x² + 23x + 36
C=2pir
arclength/circumference=centralangle/2piradians
14/2pir=6/2pi
7/pir=3/pi
times pir both sides
7=3r
divide by 3 both sides
7/3=r
well,
um
the answer is B
