Answer:
B) Sometimes
Step-by-step explanation:
Answer:
<u>Height = 3 inches and Base length = 7 inches</u>
Step-by-step explanation:
1. Information provided to answer the question correctly:
Base of the triangle = x+ 4
Height of the triangle = x
Area of the triangle = 10.5 inches²
2. Find the base length and height
Let's recall the formula of the area of a triangle:
Area = (Base * Height)/2
Replacing with the values we know:
10.5 = x (x + 4)/2
21 = x² + 4x
x² + 4x - 21 = 0
(x + 7) (x - 3) = 0
(x₁ + 7) = 0 ⇒ x₁ = -7
(x₂ - 3) = 0 ⇒ x₂ = 3
We take x₂ as the answer because x₁ = -7 is not a valid height.
<u>Height = 3 inches and Base length = 7 inches</u>
The answer is 2.16 because 12.62 + 0.34 = 12.96 then 12.96 divided by 6 = 2.16 (please make me brainlyest)
Answer:
2.25
Step-by-step explanation:
4 goes into 9 2 times with one left over 1 divided by 4 is 0.25
Answer:
D.
Step-by-step explanation:
f(x) = ![\sqrt[3]{4x}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B4x%7D)
g(x) = 2x + 3
(x) = 'f' divided by 'g'
![\frac{\sqrt[3]{4x} }{2x+3}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B3%5D%7B4x%7D%20%7D%7B2x%2B3%7D)
Substitute.
x cannot be -
because that would create a zero in the denominator.
That's a no-no.
It makes it 'undefined'
