What is the area of a Squares?
- (Side) (Side) square units make up a square's area. When the diagonal, d, is known, the area of a square is equal to d22 square units.
- For instance, a square with four 8-foot sides has a surface area of 64 square feet (ft2).
No, the perimeter and area of a square can be found using the length of just one side .
A) CD = 5 units
CD = √( 8 -4)² + ( 5 - 2 )² = √ 16 + 9
CD = √25 = 5
B) P = 4
P = 4 × 5 = 20 units
A = ( 5 )² = 25 units²

Answer:
x = 75
Step-by-step explanation:
Assuming the angles are equal ( bisected means divided in half)
2x-5 = 145
Add 5 to each side
2x-5+5 = 145+5
2x = 150
Divide by 2
2x/150/2
x = 75
You would just divide 36 by 4 and 2. So you will need (4 to 2) an 18 to 9 ratio.
Answer:
x = 6 or x = -7
Step-by-step explanation:
Solve for x over the real numbers:
x^2 + x - 42 = 0
The left hand side factors into a product with two terms:
(x - 6) (x + 7) = 0
Split into two equations:
x - 6 = 0 or x + 7 = 0
Add 6 to both sides:
x = 6 or x + 7 = 0
Subtract 7 from both sides:
Answer: x = 6 or x = -7
