Present area = 120 * 80 = 9600 ft^2 so the new area will be 9600 + 4400 = 14000
So if increase in length = x we have
(x + 120)(x + 80) = 14,000
x^2 + 200x + 9600 - 14000 = 0
x^2 + 200x - 4400 = 0
x = 20 feet answer

Answer:
C. 139°
Step-by-step explanation:
Given:
m<A = 62°
m<B = 77°
Required:
Find m<1
Solution:
Since ∆ABC is similar to ∆DEF, therefore:
<A ≅ <D, which means m<D = 62°
<B ≅ <E, which means m<E = 77°
<C ≅ <F
Therefore, based on exterior angle theorem:
m<1 = m<D + m<E
m<1 = 62° + 77° (substitution)
m<1 = 139°
Answer:
y = -2x + 1
Step-by-step explanation:
The equation is in standard form, first, we need to convert it to slope-intercept form.
5 = -10x - 5y
5 + 10x = -5y
Divide both sides by -5 to isolate y variable.
y = -2x - 1
If the line is parallel, the slope remains the same.
To find the y-intercept, you need to plug the values of x and y into the equation, which is y = 2x + b
5 = -2(-2) + b
5 = 4 + b
1 = b
The equation is -2x + 1
If it doesn't have 4 sides it is not a square
