Answer:

Ummmm what’s the question?

Step-by-step explanation:

I will edit after you tell me what your question is.

Btw God bless you.have a great day!

When the side of a square is decreased in length by 1 foot, its area is 8 ft^2. The length of a side of the square is 1 + 2√2.

Delvig [45]

Let us assume for starters that it is true.

The area of the square is s^2, so that is where you start.

(1 + 2*sqrt(2) ) ^2 = 1 + 4*sqrt(2) + 8 Taking 1 away form that does not leave you with 8.

Let's start again.

If all sides are reduced by 1 , but the square is retained, then the length of the side is 2sqrt(2). Now we have

s^2 = (2sqrt(2) )^2 = 4 * 2 = 8

The question is really not worded clearly enough to give an answer. I think it's true, but the language has to be twisted a bit.

Answer: I'd answer true, but don't be surprised if it is not interpreted the way I did on my second try.

2|y+3|-8=0<br> Solve the absolute value equation and enter the solution in set notation.

UNO [17]

2|y+ 3| = 8
|y+3| = 4

y = 1, 7 or -7

hope this helps

Jimmy is selling used books at a yard sale. A customer buys 9 books at a cost of $0.75 each and pays with a $20.00 bill. Jimmy m

KatRina [158]

C
Because .75 times 9 would give you the price of the books and then you would have to add C, the amount left to get to 20.

PLEASE HELP!!!!

wel

Answer:

Mike is not right

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared

Let

z----> the scale factor

x----> surface area of the enlarged rectangular prism

y-----> surface area of the original rectangular prism

$z^{2}=\frac{x}{y}$

In this problem we have

$z=2$

substitute

$2^{2}=\frac{x}{y}$

$4=\frac{x}{y}$

$x=4y$

The surface area of the enlarged rectangular prism is 4 times the surface area of the original rectangular prism

therefore

Mike is not right

<em>Verify with an example</em>

we have a rectangular prism

$L=5\ m$

$W=2\ m$

$H=3\ m$

The surface area of the prism is equal to

$SA=2(LW)+(2L+2W)H$

substitute the values

$SA=2*(5*2)+(2*5+2*2)*3=62\ m^{2}$

If he doubles each dimension of any rectangular prism

then

the new dimensions will be

$L=5*2=10\ m$

$W=2*2=4\ m$

$H=3*2=6\ m$

The new surface area will be

$SA=2*(10*4)+(2*10+2*4)*6=248\ m^{2}$

$248/62=4$

therefore

The surface area of the enlarged rectangular prism is 4 times the surface area of the original rectangular prism
