Answer:
0 ft < w ≤ 7 ft
Step-by-step explanation:
A=wl, where w, l >0
A≤175 ft²
l= w+18
w(w+18)≤175
w²+18w-175≤0
zeros of are -25 and 7
(w + 25)*(w - 7) ≤ 0
w+25≤0, w-7≥0 ⇒ w ⊂ ∅
w+25≥0, w-7≤0 ⇒ -25 ≤ w ≤ 7,
as w>0, we have answer: 0 < w ≤ 7

Answer:0.235
Step-by-step explanation:
Take the decimal point and move it to the left twice and you get your answer
The formula for the surface area of a rectangular prism is
A= 2(wl+hl+hw)
We are given the height =2cm, width= 5cm, and length= 10cm. All you have to do is plug this info in!
A= 2(wl+hl+hw)
= 2[(5)(10)+(2)(10)+(2)(5)]
= 2(50+20+10)
= 2(80)
=160 cm squared
