Answer:
The answer to your question is Area = 3240 ft² or Area = 360 yd²
Step-by-step explanation:
Data
length = 30 yd
width = 36 ft
Area = ? ft²
Area = ? yd²
Process
1.- Convert the units
1 yd --------------------- 3ft
30 yd ------------------ x
x = (30 x 3)/1
x = 90 ft
1 yd ------------------- 3 ft
x ------------------- 36 ft
x = (36 x 1) / 3
x = 12 yd
2.- Calculate the area of the rectangle in ft²
Area = length x width
-Substitution
Area = 90 x 36
= 3240 ft²
3.- Calculate the area in yd²
Area = 30 x 12
= 360 yd²

Answer:
x = 9 or x = -21
Step-by-step explanation:
Solve for x over the real numbers:
x^2 + 12 x - 189 = 0
The left hand side factors into a product with two terms:
(x - 9) (x + 21) = 0
Split into two equations:
x - 9 = 0 or x + 21 = 0
Add 9 to both sides:
x = 9 or x + 21 = 0
Subtract 21 from both sides:
Answer: x = 9 or x = -21
Answer:
see below
Step-by-step explanation:
CM is the bisector of ∠AMB
<u>bisector means divide into two equal parts.</u>
so x + 20 = 3x - 40
<u>solve for x:</u>
- x + 20 = 3x - 40 (combine similar terms)
- 20 + 40 = 3x - x (simplify)
- 60 = 2x (divide 2 both sides)
- x = 60/2
- x = 30
<u>now substitute x=30 back into the equation</u>
- x + 20 = 3x - 40
- 30 + 20 = 3(30) - 40
- 50 = 90 - 40
- 50 = 50 ------>> both are equal
