Answer: 44 ft
Step-by-step explanation:
if you add up the right square it adds up to 16 4+4+4+4 all sides are equal since its a square.
The left rectangle is
8+8=16
6+6=12
16+12=28
Now you add the square on the right to the square on the left which is
28+16= 44 ft

Write the equation of a line that goes through the points (-5,6) and (10,-6). The final answer should be in Slope Intercept Form.
Answer:
y=-4/5x+2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-6-6)/(10-(-5))
m=-12/(10+5)
m=-12/15
simplify
m=-4/5
y-y1=m(x-x1)
y-6=-4/5(x-(-5))
y-6=-4/5(x+5)
y=-4/5x-20/5+6
y=-4/5x-4+6
y=-4/5x+2

Which of the following is equivalent to:
−−(2+5)−(3−7)?
Answer:
You haven't provided expressions, so I can work out the problem for you. When we divide fractions, remember always "keep, switch, flip!" That's what we're gonna do here. We keep the 2/5, switch the sign to multiplication, and flip the 7/8 to 8/7. Therefore, we have 2/5*8/7. That gives us 16/35. Hope this helps!

Solve for x
TS = 2x - 6
CE = 3x - 6
Use midpoint theorem :- The line segment in a triangle joining the midpoint of two sides of the triangle is said to be parallel to its third side and is also 'half of the length of the third side'.
So,
2x - 6 = ½ (3x - 6)
2x - 6 = 3x/2 - 3
2x - 3x/2 = -3 + 6
½ x = 3
x = 3 × 2
x = 6

Don’t understand this anyone help I will give Brainyest thing
Answer:
11.8 meters
Step-by-step explanation:
The triangle drawn is a right triangle. Two of its side lengths are given. The Pythagorean theorem tells you how those relate to the third side.
The sum of the squares of the legs of the triangle is equal to the square of it hypotenuse.
(?)² + 34² = 36²
(?)² + 1156 = 1296 . . . evaluate the squares
(?)² = 140 . . . . . . . . . . subtract 1156 from both sides
(?) = √140 . . . . . . . . . take the square root
(?) ≈ 11.8 . . . meters
The length of the shadow is about 11.8 meters.

Answer:
x-intercept: -3 y-intercept: 3
Step-by-step explanation:
Substitute 0 for both variables.
-(0)=3
(0)=3
Answer:
x intercept: [tex](-3,0)[/tex] y-intecept: [tex](0,3)[/tex]
Step-by-step explanation:
So their is two ways to do this.
OPTION 1:
Turn the standern form into slope intercept.
[tex]-x+y=3[/tex]
[tex]y=3+x[/tex]
When [tex]y=0, x=-3[/tex]
Therefore, the y-intercept is 3, and the x-intercept is -3
OPTION 2:
Graph the eqaution, and see where it intercepts
Using desmos, you can graph the equation, then see where it intercepts
It intercepts the x-axis at -3, and the y-axis at 3
Solve the equation for x.

What is the area, in square units of the composite figure?
Enter your answer as a number, like this: 42
Answer:
280
Step-by-step explanation:
first, find the area of the triangle
formula: 1/2 (base × height)
so the area of the triangle is
= 1/2 (16×5)
= 1/2 (80)
= 40
then, find the area of the rectangle
formula: length × breadth
the area of the rectangle is
= 15 × 16
= 240
the area of the composite figure is the sum of the areas of the triangle and rectangle
= 40 + 240
= 280

The oblique prism below has an isosceles right triangle base.
An oblique right triangular prism is shown. The triangular bases have 2 sides with a length of x. The length of they hypotenuse is unknown. The distance from the 2 triangular bases is (x + 3). The vertical height of the prism is (x + 2).
What expression represents the volume of the prism, in cubic units?
One-halfx3 + x2
One-halfx3 + Three-halves x2
x3 + x2
x3 + 3x2
The volume of the prism, in cubic units is 1/2x³ + x²
The volume of the oblique prism is given as:
V = Base area * Height
Given the following
Height = x + 2Base area = area of the triangleBase area = 1/2 (x*x)
Base area = 1/2 x²
Get the volume of the prism;
Volume of the prism = 1/2(x²)(x+2)
Volume of the prism = 1/2(x³+2x²)
Volume of the prism = 1/2x³ + 1/2(2x²)
Volume of the prism = 1/2x³ + x²
Hence the volume of the prism, in cubic units is 1/2x³ + x²

What is the slope of the line that passes through the points (5, 6)(5,6) and (5, 9) ?(5,9)? Write your answer in simplest form.
Answer:
Step-by-step explanation:
Slope is defined as the "Rise" over the "Run" of a straight line. The Rise is the change in y, and the Run is the change in x. For the given points:
(5,6) and (5,9) the Rise and Run are (going from left to right).
Rise (9-6) = 3
Run = (5-5) = 0
The slope is 3/0, which is undefined (can't divide by zero).
Alejandro has just gotten a new job. The relationship between the number of hours he works, xx, and his total earnings, yy, is represented by the graph below.

Total Earning (in dollars)
(4 , 90)
The unit rate is 4 hours per dollar
The unit rate is 22.5 hours per dollar
The unit rate is $90.00 per hour
The unit rate is $22.50 per hour
The statement that is true about the graph as it relates the unit rate is:
d. The unit rate is $22.50 per hour
How to find Unit RateUnit rate of a relationship between two variables, x and y, that are proportionally related can be found using k = y/x, where k is the unit rate.
Given that:
x = hours he worked
y = his total earnings
We are told that (4, 90) is a point on the graph.
Using the point, (4, 90), we can find the unit rate as shown below:
k = y/x = 90/4
k = 22.5
Therefore, the statement that is true about the graph as it relates the unit rate is:
d. The unit rate is $22.50 per hour
