Step-by-step explanation:
area of ∆ = .5*b*h
b= x+5
h= x-5/2
let's do (x+5) * (x-5/2)
x^2+5x-5/2x-25/2
x^2+5/2x-25/2
area = .5x^2+5/4x-25/4
Answer:
The answer is option 2.
Step-by-step explanation:
You have to substitute the expressions into x :
h(x) = x + 4
h(x - 3) = (x - 3) + 4
h(x - 3) = x - 3 + 4
h(x - 3) = x + 1
32.5* +16* =48.5*

This value of "a" is exactly the y-coordinate of the vertex of the parabola
y = x%5E2+%2B+4x++-+31.
To find it, complete the square:
x%5E2+%2B+4x++-+31 = %28x%2B2%29%5E2+-+4+-+31 = %28x%2B2%29%5E2+-+35.
So, this value of "a" is a = -35.
Figure. Plot y = x%5E2+%2B+4x++-+31.
Answer:
<u>(x² + 4x + 6)/ 3x + 12</u>
<u>This is the most simplified form</u>
Step-by-step explanation:
Let's simplify the expression:
(x + 6)/(x + 4) + (x - 3)/3
Least Common Denominator : 3 * (x + 4)
[3 * (x + 6) + (x - 3) (x + 4)]/ 3 * (x + 4)
Solving parentheses:
[3x + 18 + x² - 3x + 4x - 12]/ 3 * (x + 4)
Like terms:
<u>(x² + 4x + 6)/ 3x + 12</u>
<u>This is the most simplified form</u>
