Mr. smith wants to know if he can fit 4 trapezoid tables in a room. what is the total area of 4 trapezoid tables?

32 ft^2

Step-by-step explanation:

Area of a trapezoid: (b1 + b2 /2 )h

a= (3+5/2)2

8/2= 4

4*2= 8

8 is the area of a trapezoid, to find area of 4 trapezoid multiply by 4

4*8= 32ft

arithmetic sequence: a sequnce in which the diffrence between any two consecutive terms is the same

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
