A trapezoid has a height of 6 inches, an area of 120 square inches, and one base measuring 13 inches. Find the length of the oth
kirill [66]

Answer:

27

Step-by-step explanation:

Givens

b1 = 13

b2 = ?

h = 6

Area = 120

Formula

Area = (b1 + b2) * h/2         Multiply by 2

2Area = (b1 + b2)*h           Divide by h

2Area/h = b1 + b2              Subtract b1 from both sides

2Area/h - b1 = b2

Solution

2*120 / 6 - 13 = b2

40 - 13 = b2

b2 = 27

It is always handy to solve an equation in the form that finds the unknown on one side. It makes the solution much easier.

Multiply this expression and check:(4y^3+4y^2+8)(6y-4)
emmasim [6.3K]
(4y³ + 4y²+8)(6y - 4)

Simplify.

24y⁴ - 16y³ + 24y³ - 16y² + 48y - 32

Add like terms.

24y⁴ + (-16y³ + 24y³) -16y² + 48 - 32

Simplify.

24y⁴ + 8y³ - 16y³ + 16

Rates and ratios simalar
Alex777 [14]
Rate is closer to a constant pattern , example: I'm walking at a rate of 2 miles an hour.

Ratio is related to the proportion of two or more objects, example: The ratio for a perfect tang juice is 1 packet of tang dust thingy for 1.5 liters of water.

Hope it helps :)
