A rectangle's length is 4 more than twice its width. Its
area is 240 square centimeters.
Complete the work to find the dimensions of the
rectangle.
w(2w + 4) = 240
2w2 + 4w = 240
2w2 + 4w - 240 = 0
2(w + 12)(w - 10) = 0
What is the width of the rectangle?
2w + 4 A = 240 cm2
What is the length of the rectangle?
w
Answers
Answer:
Step-by-step explanation:
width = w
Length = 2w + 4
Area = 240 sq. cm
length * width = 240
(2w + 4) * w = 240
2w *w + 4*w = 240
2w² + 4w = 240
2w² + 4w -240 = 0
2(w²+2w - 120) = 0
2(w² + 12w - 10w - 10*12)=0
2 (w[w + 12] - 10[w + 12] ) = 0
2 (w + 12) (w-10) = 0
Ignore (w + 12) because measurement wont be in negative value
w - 10 = 0
w = 10
Width = 10 cm
length = 2w + 4 = 2*10 + 4 = 20 + 4
Length = 24 cm
Answer:
Width = 10
Length = 24

Find the solution to the system of equations y=2x+1 y=x^2+2x-15
Answers
Answer:
x = 4 OR x = -4
Step-by-step explanation:
To find the solution, you can set both equations equal to one another:
(1) y=2x+1; (2) y=x^2+2x-15
2x+1 = x^2+2x-15
Then solve for the x-values that make this true.
2x+1 = x^2+2x-15
1 = x^2 - 15
16 = x^2
x = 4 OR x = -4

I had this exact question on a test and got it right
The maximum number of large binders she can buy is 5.
What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
Given that:-
Allison is buying binders for school. Small binders cost $3 each, and large binders cost $5 each. If Allison needs to buy at least 12 binders and has no more than $45 to spend, what is the maximum number of large binders she can buy?From the given data we can form the equation let n1 and n2 are the numbers of the small and the large binders and Sb and Lb are the cost of each binder.
n₁Sb + n₂Lb = 45 ................................1
n₁ + n₂ = 12
Now put the value of n₁ in equation 1.
( 12 - n₂ )3 + 5n₂ = 45
36 - 3n₂ + 5n₂ = 45
2n₂ = 9
n₂ = 4.5
n₂ ≅ 5
Therefore the maximum number of large binders she can buy is 5.

What is mean by Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
We have to given that;
The radius of the partial circle with center A is,
⇒ 4 feet.
Now,
We know that;
Perimeter of circle = 2πr
Here, r = 4 feet
⇒ Perimeter of circle = 2πr
⇒ Perimeter of circle = 2 × 3.14 × 4
⇒ Perimeter of circle = 25.12 feet
And, Area of circle = πr²
⇒ Area of circle = 3.14 × 4²
⇒ Area of circle = 50.24 feet²
Thus, The perimeter of the figure is, 25.12 feet
And, the area of the figure is, 50.24 feet²
