Length times width equals area of a rectangle

Length=3x

Width=x

(3x)(x)=75

3x squared=75

x=5

Length=3(5)

Length=15

Width=5

Perimeter=2(length plus width)

Perimeter=2(15+5)

=2(20)

=40

Plz help me with all 4 questions this is worth 10

Hello! I can help you with this! It asks for a ratio, so we have to solve it in that format. Although, there are different ways of solving it.

1. Okay. So a ratio for this would be 3/4 : 5/6. To divide fractions, we must keep the first fraction the same, change the division into a multiplication symbol, and flip the second fraction over. So it would look like this: 3/4 * 6/5. Multiply straight across (n*n/ d*d). When you do that, you get 18/20 or 9/10 in simplest form. The landscaper's rater is 9/10 acres per hour.

2. The ratio for this question is 9/4 : 1/2 For the next question, we repeat the steps for dividing fractions. Keep, Change, Flip. 9/4 * 2/1 is 18/4 or 4 1/2 in simplest form. Sally's running speed is 4 1/2 miles per hour.

3. Okay. Going back to question #1, the unit rate was 9/10 acres per hour. All we have to do now is multiply that number by 4. To multiply fractions, do it straight across. 9/10 * 4/1 is 36/10 or 3 3/5 in simplest form. A landscaper can mow 3 3/5 acres in 4 hours.

4. Then we repeat the steps done in question #3, and incorporate it in this problem. Going back to question #2, the unit rate was 4 1/2 miles per hour. All we have to do is multiply by 3. 9/2 * 3/1 is 27/2 or 13 1/2 in simplest form. Sally can run 13 1/2 miles in 3 hours.

2/3 -walnuts

1/6-cranberries

2/3+1/6

common denominator-12

2/3 ·4/4=8/12

1/6 · 2/2= 2/12

8/12+2/12=10/12

10/12=5/6

Help me please!!!!!!!!
aleksley [76]

prime factor stuff.. 32 = 8*4 = (4*2)*(2*2) = (2*2*2)*(2*2)

3 √(2*2*2*2*2*x*x*x*x*z) = 3 √(2²*2²*2*x²*x²*z)

It's a square root so move one of each pair outside the radical.

3*2*2*x*x √(2*z)

12x² √(2z)
