Answer:
Step-by-step explanation:
Alright, lets get started.
We first need to find the surface area of the ramp without its base.
The ramp consists 4 sides two triangles and two rectangles.
Area of 1 triangle = 
Area of 2 triangle = 42
Area of top rectangle = 
Area of back rectangle = 
So total area = 
square feet
We are asked to paint two coats of paint means we have to double the area.
So the double area is = 
80 square feet requires = 1 quart of paint
994.8 square feet requires = 
12.4 quart can't be purchased so complete number of quart will be 13 quart. : Answer
Hope it will help :)
Step-by-step explanation:
15a)
Subtract both sides by 21
15b)
7 and -3 multiply to -21 and add to 4
The factors are (x+7)(x-3)
15c)
x+7 =0
x=-7
x-3=0
x=3
Answer:
We have the system of equations:
y = -2*x
y = 2*x + 4.
To solve it by graphing, you need to graph both lines and see in which point the lines intersect each other.
You can see it in the image below. (blue is y = 2*x + 4, and green is y = -2*x)
We also can calculate the solution with math, let's do that:
y = -2*x
y = 2*x + 4.
We can replace the first equation in the second one, to get:
-2*x = 2*x + 4
Now let's solve this for x
-2*x -2*x = 4
-4*x = 4
x = 4/-4 = -1
Evaluating this in one of the equations we get:
y = -2*-1 = 2
Then the solution is the point (-1, 2), exactly what we can see in the graph.

<u>Answer:</u>
The correct answer option for this is: False.
<u>Step-by-step explanation:</u>
We are given the following statement which we are to determine whether its true or false:
<em>In order to form a negation, just add "not" to a statement or take "not" out of a statement if it already exists.</em>
To form a negation, we add the word 'not' to a statement - this part of the given sentence is true.
While 'or take "not" out of a statement if it already exists' is false which makes the whole sentence false.
