Answer:
A. 5x^2 − 2x − 24 = 0
Step-by-step explanation:
height = 5b-2
b =x
We can rewrite the height as
h = 5x-2
We know the formula for area of a triangle
A = 1/2 bh
A =1/2 x * (5x-2)
Distributing the x
A= 1/2 (5x^2 - 2x)
We know A =12
12 = 1/2 (5x^2 - 2x)
Multiply each side by 2
12*2 = 2*1/2 (5x^2 - 2x)
24 = 5x^2 - 2x
Subtract 24 from each side
24-24 = 5x^2 - 2x-24
0 = 5x^2 - 2x-24
Given:
The two functions are:


To find:
The function
.
Solution:
We have,


Now,


Therefore, the correct option is B.
Answer:
y = 4x² -19x -5
Step-by-step explanation:
When you graph it (or use an appropriate tool), it can help us to figure out that the equation is:
y = 4x² -19x -5
(Quadratic regression = the process of determining the equation of a parabola that best fits a set of data)

Answer:
456 sq. units
Step-by-step explanation:
Formula for the area of the square:
b(base)*h(height)
b=21
h=16
21*16=336
Formula for the area of the triangle:
b*h/2
b=36-21=15
h=16
15*16/2=120
Add the two shaped together:
336+120=456
Label your answer: 456 sq. units
