x = 7Area of shaded region = 162 square unitsYou may need to leave off the "square units" portion.
=============================================
Explanation:
For now, ignore the smaller rectangle and its dimensions. The larger rectangle has sides 3x and x+5, which I'll call the length and width.
L = 3x
W = x+5
The perimeter of any rectangle is P = 2(L+W). Plug in those values of L and W, and also the given perimeter P = 66. Isolate x.
P = 2(L+W)
2(L+W) = P
2(3x+x+5) = 66
2(4x+5) = 66
8x+10 = 66
8x = 66-10
8x = 56
x = 56/8
x = 7
-------------------
Now that we know x, we can find the area of the rectangles.
As you probably can guess, the shaded region is the difference of the two areas.
A = area of larger rectangle
A = (length)*(width)
A = (3x)*(x+5)
A = (3*7)*(7+5)
A = 252
B = area of smaller rectangle
B = (x+3)*(x+2)
B = (7+3)*(7+2)
B = 90
C = area of shaded region
C = A - B
C = 252 - 90
C = 162 square units is the area of the shaded region.

Answer:
f(x+3) +7
Step-by-step explanation:
We move the green graph 3 units to the left f(x-h) where h is how many units moved. We are moving 3 units to the left so h is -3 f(x - -3)
f(x) becomes f(x+3)
Then we move up 7 units

Can someone help me with this question and help me find out what the "a" does in the problem y=a(x-h)^(2)+k
Answer:
See below (and attached file)
Step-by-step explanation:
The value of [tex]a[/tex] in the equation [tex]y=a(x-h)^2+k[/tex] represents how much a vertical parabola will stretch or compress, as well as whether it opens upward or downward:
If [tex]0<|a|<1[/tex], it is a horizontal stretch
If [tex]|a|>1[/tex], it is a horizontal compression
If [tex]a<0[/tex], the parabola opens downward
If [tex]a>0[/tex], the parabola opens upward
The file attached shows a graph with different examples of what happens to a parabola when the value of [tex]a[/tex] changes.
What is the average rate of change for this quadratic function for the interval
from x = 1 to x = 3?
O A. -8
B.-4
O O
C. 8
O D. 4
==========================================================
Explanation:
The table says that when x = 1, the output is y = -2.
So the point (1, -2) is on the parabola.
The table also says that point (3, -10) is on the parabola. We're focusing on this because x = 3 is the other endpoint.
Find the slope of the line through those two points. The slope here is the same as the average rate of change.
m = (y2 - y1)/(x2 - x1)
m = (-10 - (-2))/(3 - 1)
m = (-10 + 2)/(3 - 1)
m = -8/2
m = -4 is the slope, and therefore, the average rate of change from x = 1 to x = 3.

Find the equation of a line that passes through the point (3,6)
with slope 2.
Answer:
y = 2x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 , then
y = 2x + c ← is the partial equation
To find c substitute (3, 6) into the partial equation
6 = 6 + c ⇒ c = 6 - 6 = 0
y = 2x ← equation of line
The equation of line that passes through the point (3,6) with slope 2 is;
⇒ y = 2x
Given that;
The point is (3, 6)
The slope of line = 2
We have to find the equation of a line that passes through the point (3,6) with slope 2.
What is equation of line?
The equation of line that passes through the point (x₁, y₁) with slope m is;
y - y₁ = m (x - x₁)
The point is (3, 6)
The slope of line = 2
The equation of line that passes through the point (x₁, y₁) = (3,6)
with slope(m) = 2 is;
y - y₁ = m (x - x₁)
y - 6 = 2 (x - 3)
y - 6 = 2x - 6
Add 6 on both sides;
y = 2x
Hence, The equation of line that passes through the point (3,6) with slope(m) 2 is;
⇒ y = 2x

Answer:
x = 2, P = 22 cm, A = 21 cm²
Step-by-step explanation:
The 2 legs of the triangle are congruent , then
6x - 4 = 8 ( add 4 to both sides )
6x = 12 ( divide both sides by 6 )
x = 2
perimeter = 8 + 8 + 6 = 22 cm
Area = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 6 and h = 7 , then
A = [tex]\frac{1}{2}[/tex] × 6 × 7 = 3 × 7 = 21 cm²
Answer:
x = 2
Perimeter = 22 cm
Area = 21 cm²
Step-by-step explanation:
=> We know that the 2 side lengths of the given triangle are congruent, because of the congruency mark theorems, therefore to solve for x first, we can say;
6x - 4 = 8
6x = 8 + 4
6x = 12
x = 12/6
x = 2
Now that we know the side lengths of the triangles are 8, 8 and 6, we can find the perimeter;
Side 1 + Side 2 + Side 3 = Perimeter
8 + 8 + 6 = Perimeter
22 = Perimeter
Lastly to find the Area of the triangle, follow the formula of;
A = 1/2 (b * h)
A = 1/2 (6 * 7)
A = 1/2 (42)
Area = 21
Hope this helps!
