Just answer it as soon as possible

Multiply by 3 in the first equation and then you can cancel out the +3y and -3y to get the x answer. After that, you can do the same with the y by multiplying -2 in the first equation to cancel out the +2x and the -2x. Do you understand?

Expand. (1-4m)(m^2-3m+8) your answer should be a polynomial in standard form.

sergiy2304 [10]

Answer:

13m²−35m+8−4m³

Step-by-step explanation:

Expand (1 − 4m)(m² − 3m + 8) by multiplying each term in the first expression by each term in the second expression.

1m² + 1 (−3m) + 1 ⋅ 8 − 4m ⋅ m² − 4m (−3m) − 4m ⋅ 8

Simplify terms.

13m²−35m+8−4m³

You are building a brick patio. the length of the patio is (x+11) feet.

Romashka-Z-Leto [24]

The expression that represents the width of the patio is (x+3) feet

<h3>Calculating area</h3>

From the question, we are to determine the width of the patio

The area of the patio = Length of the patio × Width of the patio

From the given information,

Length of the patio = (x+11) feet

Area of the patio = x^2+14x+33 = x²+14x+33

Putting the parameters into the formula,

x²+14x+33 = (x+11) × Width of the patio

∴ Width of the patio = (x²+14x+33) / (x+11)

First, we will factor x²+14x+33

x²+14x+33

x²+11x+3x+33

x(x+11) +3(x+11)

(x+3)(x+11)

Thus,

Width of the patio = [(x+3)(x+11)] / (x+11)

∴ Width of the patio = (x+3) feet

Hence, the expression that represents the width of the patio is (x+3) feet
