Answer:

A=12x²+13x-14

Step-by-step explanation:

Area=Length×width

A=(4x+7)(3x-2)

A=4x(3x-2)+7(3x-2)

A=12x²-8x+21x-14

A=12x²+13x-14

Matt is cutting quilt squares measuring 3 inches on each side. He wants to use them to make a rectangular wall hanging measuring
Andrei [34K]

Answer:

Matt will need 10176  square quilts to cover the wall

Step-by-step explanation:

To answer this perfectly, we will have to first convert everything to the same unit.

dimensions of the quilt squares = 3 inches

Length of the wall = 1 yard = 36 inches

Breadth of the wall = 212 feet = 2544 inches.

The next step, is to find the area of the wall that Matt is covering.

Area of wall = length X breadth = 36 X 2544 = 91584in ^{2}

We will also find the area of the square quilts. This is given as length X length = 3^{2}=9 in^{2}

to get the number of square quilts that will cover that area, we will have to divide the area of the wall by the area of the quilts

= 91584 /9 = 10176 quilts

Matt will need 10176 quilts to cover the wall

Which equation is correct using "is not equal to'' (≠)?
romanna [79]

65/5=13-3=10       27-17=10

72/6=12-1=11         54-43=11

88/8=11-2=9         27-18=9

90/3=30-8=22    34-10=24

So, that makes "90 ÷ 3 − 8 _____ 34 − 10" not equal.

Hope this helps! Stay Safe!
