<span>Perimeter of a rectangle: 2(l + w)
</span>
2(l + w) ≥ 30 in
<span>
Simplify- divide both sides by 2.
l + w ≥ 15 in
Substitute (w + 3) into l so only 1 variable is used.
(w + 3) + w ≥ 15 in
Simplify further- add variables and subtract 3 from both sides.
2w ≥ 12 in
Divide both sides by 2.
w ≥ 6 in
Answer: D</span>
Answer: yay
Step-by-step explanation:
So to find the answer we need to know the area of the deck by splitting each individual part into smaller shapes.
So for the rectangle up top we have: 50ft
Then for the triangle: 12.5ft
Then another rectangle above the triangle which is: 50 ft
Then the biggest rectangle is: 375ft
We would add this all together.
50+50+375+12.5=487.5
So one gallon costs $34 and covers 200 ft
So 487.5/200=2.437->multiply it by 34 and get 82.8 or $83
Your answer is $83
Answer:
x=8
Step-by-step explanation:
add 5+1 and you get 6. To find what minus 6 equals 2 add 2 to 6 giving you 8
Answer:
factors are
21 and x
Step-by-step explanation:
equation 9 × 2 + 21x - 18
terms 9 , 2, 21x, -18
factors 21x = 21 and x
