C and D because I just know
The values of a, b, and c are -4,0 and 0 and the parabola opens downward with y-intercept (0,0).
we have
y=-4x^2
<h3>What is the standard form of the quadratic equation?</h3>
The quadratic equation in standard form is equal to
ax^2+bx+c=0
So,In this problem
a=-4, b=0 and c=0
The y-intercept is the value of y when the value of x is equal to zero
y=-4(0)^2=0
The y-intercept is the point (0,0)
The coefficient a is negative, therefore the parabola opens down.

Answer:
D. 4(11y + 22)
Step-by-step explanation:
4 times 11 is not 45 so D is the answer
Answer:
Step-by-step explanation:
The shorter sides of the porch can be found by subtracting 2.5m from 3m to get .5m; the longer sides are found by looking at the opposite end of the tent at the rectangle with a 1 inside of it. That 1 indicates the length of the rectangle, which is the same for the porch's length. That means that the perimeter is .5+1+.5+1 which is 3m total.
Answer:
multiply both sides by
Step-by-step explanation:
Given
x - 8 = 12
first step
Add 8 to both sides
x = 20
second step
Multiply both sides by to clear the fraction
x = × 20 = 30
