The width of a poster is 8cm less than the length. The perimeter is more than 184

mart [117]

Let the length be x
width = x - 8
Perimeter = Length + Length + Width + Width

x + x + x - 8 + x - 8 > 184
4x - 16 > 184
4x > 184 + 16
4x > 200
x > 50

Therefore:
Length > 50
Width > 50 - 8
Width > 42

Ans: Length > 50, Width > 42

S=_ft ?? Please also tell me how to do it

irina1246 [14]

Answer:

$70ft^2$

Step-by-step explanation:

Surface area is the sum of all sides of the area. Since it is a rectangular prism, each surface area will be multiplied by two to account for the opposite side (ex. top and bottom are the same area).

The front/back area is $1*11$ or 11. So the sum of the areas is 22.

The right/left area is $2*1$ or 2. So the sum of the areas is 4.

The top/bottom area is $2*11$ or 22. So the sum of the areas if 44.

We add these together to find the surface area.

$22+4+44=70$

The surface area is $70ft^2$

If (3x2 + 22x + 7) ÷(x + 7) = 3x + 1, then (x + 7)( ) = . The check of the polynomial division problem shows that the product of

azamat

Answer:

$(x + 7) * (3x + 1) = (3x^2 + 22x + 7)$

Step-by-step explanation:

Given

$(3x^2 + 22x + 7) \div (x + 7) = 3x + 1$

$(x + 7) * (\ ) = [\ ]$

Required

Complete the blanks

We have:

$(3x^2 + 22x + 7) \div (x + 7) = 3x + 1$

Rewrite as:

$\frac{(3x^2 + 22x + 7) }{ (x + 7)} = 3x + 1$

Cross multiply

$(x + 7) * (3x + 1) = (3x^2 + 22x + 7)$
