The length of a rectangle is 7 ft longer than twice the width. If the perimeter is 92 ft find the length and width of the rectan

user100 [1]

Width of the rectangle is 13 ft and length of the rectangle is 33 ft

<u>Step-by-step explanation:</u>

Step 1:

Given perimeter of the rectangle = 92 ft. Let the width be x, then the length of the rectangle = 2x + 7. Use the formula for perimeter of a rectangle = 2(length + width) to find the dimensions.

92 = 2(2x + 7 + x) = 2(3x + 7) = 6x + 14

⇒ 92 = 6x + 14

⇒ 78 = 6x

⇒ x = 78/6

∴ x = 13 ft

⇒ Width of the rectangle = 13 ft

∴ Length of the rectangle = 2x + 7 = 26 + 7 = 33 ft

Can someone help me with my math homework?

See explanations

Step-by-step explanation:

6. The fraction can be written as;

$\frac{x^2}{2y} /\frac{y^2}{4} \\\\\frac{x^2}{2y} *\frac{4}{y^2} \\\\$

Divide 4 by 2

= $\frac{2x^2}{y^3}$

The fraction can be written as;

$\frac{b^2}{6} /\frac{b}{a}$

introduce product sign as

$\frac{b^2}{6} *\frac{a}{b} \\\\=b*a/6\\=\frac{ab}{6}$

The fraction can be written as;

$\frac{x}{y} /\frac{yx}{2}$

Introduce product sign

$\frac{x}{y} *\frac{2}{yx} \\\\=\frac{2}{y^2}$

The fraction can be written as;

$\frac{x}{y^2} /\frac{x}{y} \\\\\\=\frac{x}{y^2} *\frac{y}{x} \\\\\\=\frac{1}{y}$

10.

The fraction is simplified to;

$\frac{x}{3y} /\frac{9}{x} \\\\\\\frac{x}{3y} *\frac{x}{9} =\frac{x^2}{27y}$

20 Points!!! Math Question

larisa86 [58]

Here is how to do the question,

The Remainder Theorem starts with an unnamed polynomial p(x), where "p(x)" just means "some polynomial p whose variable is x". ... If you get a remainder, you do the multiplication and then add the remainder back in. For instance, since 13 ÷ 5 = 2 R 3, then 13 = 5 × 2 + 3. This process works the same way with polynomials.

Hope that helps!!!!
