Answer 1

Answer: area = length x width

x² + 12x = l * x

A.

First, you factor x from x² + 12x

$x^(2) +12x=x(x+12)$

area = x (x+12)

area = (x+12) * x

Length = x + 12

B.

If x = 10,
l = x + 12 = 10 +12 = 22
length = 22
and
Area = x² + 12x = 10² + 12(10) = 100 + 120 = 220
area = 220

Hope this helps :)

Whats the improper fraction for 3 4/17

Answers

Answer: 55/17

Step-by-step explanation: To write a mixed number as an improper fraction, first multiply the denominator by the whole number, then add the numerator.

So here we multiply the denominator (17) by the whole number (3), then we add the numerator which is 4.

Finally, we put our new number over our old denominator and we have our answer 55/17.

Therefore, 3 and 4/17 can be rewritten as the improper fraction 55/17.

A square piece of fabric has an area of 16x^2+40x+25 square inches. The length of each side of the fabric is cx+d, where c and d are whole numbers. Find an expression for the perimeter of the piece of fabric. Then find the perimeter when x=2.

Answers

$A=(cx+d)^2=c^2x^2+2cdx+d^2\n\nc^2x^2+2xcd+d^2=16x^2+40x+25\n\Downarrow\nc^2=16;\ 2cd=40;\ d^2=25\n\Downarrow\nc=√(16);\ cd=20;\ d=√(25)\n\Downarrow\n\boxed{c=4\ and\ d=5}\n\nThe\ length\ of\ side:cx+d=\boxed{4x+5}\n\nThe\ perimeter\ of\ the\ piece\ of\ fabric:4(4x+5)=\boxed{16x+20}\n\nFor\ x=2:\n16\cdot2+20=32+20=\boxed{52}$

Final answer:

The expression for the perimeter of the fabric is P = 16x+20. When x=2, the perimeter is 52.

Explanation:

To find the expression for the perimeter of the piece of fabric, we need to determine the length of each side of the fabric. The given expression for the area of the fabric is 16x^2+40x+25. We can factor this expression as (4x+5)^2. Since a square has all its sides equal, the length of each side of the fabric is 4x+5.

The perimeter of a square is given by the formula P = 4s, where s is the length of a side. Therefore, the expression for the perimeter of the fabric is P = 4(4x+5) = 16x+20.

To find the perimeter when x=2, we substitute x=2 into the expression for the perimeter: P = 16(2)+20 = 32+20 = 52.
