<span>width = 82 feet, length = 123 feet
First, write down equations that express what you've been given.
w = 2/3 l
p = 410
p = 2(w+l)
Since we have an expression that defines w in terms of l, substitute for w, the expression. Also substitute the known value for p in the expression.
p = 2(w + l)
410 = 2( 2/3 l + l)
Combine the l terms
410 = 2( 5/3 l)
Multiply
410 = 10/3 l
Multiple both sides by 3
1230 = 10 l
Divide both sides by 10
123 = l
So we now know the length is 123 feet.
So plug in the known value of l into the formula w = 2/3 l to get the width
w = 2/3 123 = 82</span>
Answer:
-1/7
Step-by-step explanation:
1/5 · (-2/7) = -2/35
= -2/35 · 5/2 = -10/70
simplified -10/70
-1/7
1. The fire covered 300
3 days ago
2. Today it covers twice the amount of 3 days ago so 2*300=600 (
)
3. After 3 days from today, it will have covered 2*2*300=1200
4. After 3*2=6 days from today, 2*2*2*300=2400
5. After 3*3=9 days from today, 2*2*2*2*300=4800
6. After 3*4=12 days from today, it will have covered 2*2*2*2*2*300=9600 (
)
7. We can gereralize: After 3*n days from today, it will have covered
(
)
To solve this problem to standard form means adding all those numbers together.
600,000+80,000= 680,000
680,000+10= 680,010
680,010 is your answer
Answer:
48x + 216 square inches.
Step-by-step explanation:
Area is length X width.
Area is (4x + 18)(12).
in 4x + 18, 18 comes from adding the three 6 in.
We have no values for "x", so expand the equation and simplify.
(4x + 18)(12)
= 48x + 216
