Answer:
x=4
Step-by-step explanation:
28-16=12 / 3 = 4
The perimeter is defined as the sum of all the sides of any polygon.
A rectangle is a polygon with 4 sides and 2 pairs of parallel sides. Therefore, in order to find the perimeter of any rectangle, we can either add up all the sides given to you or use a formula which states that:
P = 2L + 2W
Where,
L is the length of the rectangle and W is the width of a triangle.
For example:
A triangle with length = 5 cm and Width = 3 cm.
The Perimeter will be:
P = 2×5 + 2×3
P = 10 + 6
P = 16 cm
Answer:
slope = - 
Step-by-step explanation:
Parallel lines have equal slopes thus the slope of a parallel line will be equal to the slope of PQ
To calculate slope m use the slope formula
m = 
with (x₁, y₁ ) = P(- 2, 4) and (x₂, y₂ ) = Q(6, - 2)
m = 
= 
= -
23 x 5% =
23 x 0.05= 1.15 (total sales tax)
23 + 1.15= $24.15 (total price)
∫ √(4x - x²) dx
= 2[(4x - x²)^(3/2)] / 3(4 - 2x)
