Hallie can use the equation p = 4l + 4w + 4h to determine the sum of the lengths of the edges of a rectangular prism. She begins

to solve the equation for h but runs out of time. Her partial work is shown below: p = 4l + 4w + 4h 2. StartFraction p Over 4 EndFraction equals StartFraction 4 l plus 4 w plus 4 h Over 4. 3. StartFraction p Over 4 EndFraction equals l plus w plus h. = l + w + h h = 4. h equals StartFraction p Over 4 EndFraction minus blank. – Which expression should follow the subtraction in Hallie’s equation? (l + w) (l – w) left-parenthesis StartFraction l plus w Over 4 right-parenthesis. left-parenthesis StartFraction l plus w Over 4 EndFraction right-parenthesis.

Mrs drew wants to build a square sandbox with an area of 169 square feet. What is the total length of wood mrs. Drew needs to ma
Bezzdna [24]

Area of sandbox = 169 square feet

Area of square with side 'x' is given by the formula = x^2

We have to determine the total length of wood Drew needs to make the sides of the​ sandbox.

Total length of wood required would be equal to perimeter of sandbox.

Let 'a' be the side of the square sandbox.

So, Area of sandbox = 169

a^2 = 169

a = \sqr{169}

a = 13 feet

Total length of wood required to make sides of the sandbox = Perimeter of the square sandbox = 4 \times a

= 4 \times 13

= 52 feet.

Therefore, 52 feet of wood is required to make the sides of the square sandbox.

The larger of two numbers is 7 less than twice the
Flauer [41]

Answer:

The two numbers are 29 and 18

Step-by-step explanation:

Let x and y be the two numbers

x = 2y-7

x+y = 47

We have two equations and 2 unknowns

Substituting the first equation into the second equation

2y-7+y = 47

Combine like terms

3y -7 = 47

3y-7+7 = 47+7

3y = 54

Divide by 3

3y/3 = 54/3

y = 18

Now find x

x = 2y-7

x = 2*18 -7

x = 36-7

x = 29

The two numbers are 29 and 18
