Let x be the width of the room. I<span>f the width is 3.5 feet less than the length, then the length is x+3.5. The perimeter is x+x+x+3.5+x+3.5=4x+7.
</span>
Since the perimeter is equal to 67, then 4x+7=67, 4x=60, x=60÷4, x=15 ft and x+3.5=15+3.5=18.5 ft.
Answer: the width is 15 ft, the length is 18.5 ft.

If yo travel56mph how far will you go in2hr15min how long does it take to cover 168 miles
Alex73 [517]
2 hr 15 min = 2 \frac{1}{4} hours = 2.25 hours
"how far" means distance ... so distance = rate x time
distance = 56 x 2.25 = 126 miles

"how long" means time ... so using the same formula 
168 = 56 x time
divide both sides of the equation by 56 to solve
3 hours = time

chet needs to buy 4 work shirts,all costing the same amount .the total cost before chet appplies a $25 gift certificate can be n
Rashid [163]
So for this problem, let us use x as the cost before Chet would apply a $25 gift certificate. Based on the problem, we can see that the original cost of the product cannot be more than 75 which means that it can be equal to 75 or less than 75. We can actually express the inequality as x< or = 75 since we are looking for the cost before Chet applied the $25 gift certificate. This means that we do not need to add in the 25 yet since the question asks for the cost before the application of the discount.

Surface area of solid figures
Lilit [14]

Answer:

C. 468mm²

Step-by-step explanation:

The formula for the surface area of rectangular prism is:

A=2(wl+hl+hw)

Let's break down our variables.

L = 12mm

W = 6mm

H = 7mm + 2mm = 9mm

Now we substitute our values in the formula:

A=2((6)(12)+(9)(12)+(9)(6))

A=2(72+108+54)

A=2(234)

A=468mm^{2}
