<u>Question</u>:
A rectangle has a height of 4 and a width of x² + 3x + 2. Express the area of the entire rectangle.
<u>Given:</u>
The height of the rectangle is 4.
The width of the rectangle is 
We need to determine the area of the entire rectangle.
<u>Area of the entire rectangle:</u>
Let us determine the area of the entire rectangle.
The area of the rectangle can be determined using the formula,
Substituting height = 4 and width =
Thus, we get;
Multiplying the terms by 4, we get;
Thus, the area of the entire rectangle is 
ANSWER
Yes, it is a quadratic equation which is x² + 3x - 70 = 0
SOLUTION
Area = Length × Width
Let x be the Length, L = x
Length is 3 cm longer than its width, thus, W = x + 3
The Area is equal to 70m², thus, A = 70m²
In Mathematical representation,
A = L × W
70 = (x)(x + 3)
70 = x(x) + x(3)
70 = x² + 3x
0 = x² + 3x - 70
Since it is 12 dollars per hour, she would multiply the number of hours they were conoeing with the cost... $12. The answer is B... 12h
6 pencils = 2 rulers
1ruler= 2 eraser
12 pencil = 4 rulers
4rulers=8 eraser
so 8 erasers are equal to 12 pencils
In the given question, it is given that ramp is 17 feet long, rises 8 feet above the floor, and covers a horizontal distance of 15 feet.
And we have to find the value of tan B.
And tangent of any angle is equal to the ratio of vertical by horizontal. That is:
tanB=8/15
And that's the required missing ratio for tan B.
