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
Zanzabum

The expression Hallie wrote is not clear, because if 0 is the only number that satisfies p = 4l + 4w + 4h = l + w + h.

But if you meant to write:

p = 4l + 4w + 4h

p/4 = l + w + h

then she could get something different.

Answer:

The expression (w + h) + p/4 should follow the subtraction if Hallie's equation is

p = 4l + 4w + 4h

p/4 = l + w + h

h = -

Step-by-step explanation:

Let us solve Hallie's problem.

She can use the equation:

p = 4l + 4w + 4h

to determine the sum of the lengths of the edges of a rectangular prism. Because she begin to solve the equation for h, let us solve for h.

This means we are trying to make h the subject of the formula.

p = 4l + 4w + 4h

When you factor out 4 on the right hand side, you have

p = 4(l + w + h)

Dividing both side by 4, we have

p/4 = l + w + h

Now, subtracting (l + w) from both sides, we have

p/4 - (l + w) = h.

This can be written as:

h = - (l + w) + p/4

And that is what Hallie wanted to obtain.

Factor the polynomial.<br><br> X2-13x+30
Svetllana [295]

Answer:

<h2>\ \boxed{(x - 3)(x - 10)}</h2>

Step-by-step explanation:

{x}^{2}  - 13x  + 30

Write -13x as a difference

{x}^{2}  - 3x - 10x + 30

Factor out x from the expression

x(x - 3) - 10x + 30

Factor out -10 from the expression

x(x - 3) - 10(x - 3)

Factor out x-3 from the expression

(x - 3)(x - 10)

Hope I helped!

Best regards!!

Manny bought 12 pounds of vegetables
finlep [7]

Answer:

Manny bought 3 pounds that were not on sale

Step-by-step explanation:

If 75 % were on sale,  (100% -75% = 25%)  then 25% were not on sale  (The total has to be 100%)

Manny bought 12 pounds of vegetables

To determine how many pounds were not on sale, we take the amount of vegetables purchased and multiply by the percent that were not on sale.

12 * 25%

Change this to decimal form

12 *.25

3

Manny bought 3 pounds that were not on sale
