Answer:

The length of the missing side is 5 m

Step-by-step explanation:

In order to find this, use the perimeter formula.

P = 2L + 2W

Now input 11 as the L and 32 as P

32 = 2(11) + 2W

32 = 22 + 2W

10 = 2W

5 = W

IrinaK [193]

Answer:

D. $\sqrt[3]{5^7}$

Step-by-step explanation:

The formula for this conversion is:

$a^\frac{x}{n}=\sqrt[n]{a^x}$

Substitute the values you currently have.

$5^\frac{7}{3}=\sqrt[n]{a^x}$

Since we know that

a = 5

x = 7

n = 3

Fill the square root with this.

$5^\frac{7}{3}=\sqrt[3]{5^7}$

Janice is thinking of two numbers. She says that two times the first number plus the second number is 41. In addition, the firs

Rudiy27

Let one of the number be x and the other be y

two times the first number plus the second number is 41
2x + y = 41

the first number plus three times the second number is 73
x + 3y = 73

2x + y = 41 --------- (1)
x + 3y = 73 --------- (2)

From (1):
2x + y = 41
y = 41 - 2x ------- sub into (2)
x + 3(41-2x) = 73
x + 123 - 6x = 73
x -6x = 73 - 123
-5x = -50
x = 10 -------- sub into (1)
2 (10) + y = 41
20 + y = 41
y = 41 - 20
y = 21

Ans: x = 10, y = 21
