Answer:

w = 13

Step-by-step explanation:

Using the method of cross- multiplying

• $\frac{a}{b}$ = $\frac{c}{d}$ ⇒ ad = bc, thus

42(w + 11) = 28(w + 23) ← distribute parenthesis on both sides

42w + 462 = 28w + 644 ( subtract 28w from both sides )

14w + 462 = 644 ( subtract 462 from both sides )

14w = 182 ( divide both sides by 14 )

w = 13

Sam wants to build a wooden deck on his patio, which is in the shape of a parallelogram. The area of the patio is 280 ft2. Find the base. Round your answer to the nearest foot. (height=5x)(base=6x)

Step-by-step explanation:

Given;

Area = 280ft^2

height = 5x

Base = 6x

The area of the parallelogram A can be written as;

Area = base × height

A = b×h

Substituting the values of Area, base and height.

280 = 5x × 6x

280 = 30x^2

x^2 = 280/30

x = √(280/30)

Since the base = 6x ;

Substituting the value of x.

Base = 6x = 6(√(280/30))

Base = 18.3ft

The base is 18.3ft

Answer is : 8v^3+ 14v^2+11v+3
For cubic feet

Solution

Formula : volume base area x height

So base area = 4v^2 +5v+3
Height = 2v+1

So multiply

Volume =(4v^2+5v+3) x(2v+ 1)

The rest is below
