Answer:
x = 3
Step-by-step explanation:
3(x + 2) = 6(x - 1) + 3
Divide both sides by 3.
x + 2 = 2(x - 1) + 1
Distribute the 2 on the right side.
x + 2 = 2x - 2 + 1
Combine like terms on the right side.
x + 2 = 2x - 1
Add 1 to both sides. Subtract x from both sides.
3 = x
x = 3
Answer with explanation:
Length of side of Square = 7 cm
Area of Square = (Side)²=7²=49 cm²
Diameter of circle = 7 cm
So, Radius
cm
Area of circle = π × (Radius)²
=3.14 × (3.5)²
= 3.14 × 12.25
= 38.465 cm²
Area of shaded Region = Area of Square - Area of Circle
= 49 - 38.465
= 10.535 cm²
=10.54 cm²
Option A
Answer:
10.39 or 10.4
Step-by-step explanation:
Since this is a right triangle, you have the formula a squared +b squared = c squared where a and b are the legs and c is the hypotenuse. You plug in the values and you should get sqrt of 108 for x.
