Answer:
Step-by-step explanation:
7) The formula for determining the area of a parallelogram is expressed as
Area = base × height.
Length of base = Area/height
Therefore,
Length of base = 7/2 = 3.5 feet
8) The formula for determining the area of a trapezoid is expressed as
Area = 1/2(a + b)h
Where
a and b are the length of the bases
h is the height. Therefore
21 = 1/2(2 + 4)h
21 = 3h
h = 21/3 = 7 inches
9) Area = base × height.
Height = Area/Length of base
Height = 28/14 = 2 inches
10) a and b are 10 inches each.
Area = 1/2(a + b)h
Therefore,
35 = 1/2(10 + 10)h
35 = 10h
h = 35/10
h = 3 inches
Answer:
Your answer would be
2(13+9x)
Step-by-step explanation:
Answer:
Step-by-step explanation:
y = 4.8x + C
53.8 = 4.8(4) + C
53.8 = 19.2 + C
C = 34.6
Let's solve your equation step-by-step.
4(x−3)−5(x+1)=3
Step 1: Simplify both sides of the equation.
4(x−3)−5(x+1)=3
(4)(x)+(4)(−3)+(−5)(x)+(−5)(1)=3(Distribute)
4x+−12+−5x+−5=3
(4x+−5x)+(−12+−5)=3(Combine Like Terms)
−x+−17=3
−x−17=3
Step 2: Add 17 to both sides.
−x−17+17=3+17
−x=20
Step 3: Divide both sides by -1.
−x−1=20−1
x=−20
