Answer:

The numbers are 4 and 11.

Step-by-step explanation:

If one number is 7 more than the other, you can express that as x+7 is equal to the other number which we can call "y".

If you add "y" which is basically x+7 to x, which is one of the numbers, your equation will be x+x+7=15.

Simplify: 2x+7=15.

Subtract 7 from both sides of the equation and you have 2x=8.

Divide by 2 on both sides and x is equal to 4.

You plug 4 back into the expression "x+7".

4 plus 7 is 11.

I could use some help , i really cant do geometry :(
Gelneren [198K]

Answer:

I am not sure but for

CAE it is 65˚

CBD it is 65˚

Step-by-step explanation:

x+40=3x-10

Move the 3x to the other side by subtracting by 3x on both sides

x-3x+40=3x-3x-10

The equation now looks like this:

-2x+40=-10

Move 40 to the other side by subtracting 40 both sides:

-2x+40-40=-10-40

-2x=-50

Divide by -2 on both sides:

-2x/-2=-50/-2

x=25

Since we found out what x is we can replace x in both CAE and CBD:

For CBD: 25+40 is 65

For CAE: 3(25)-10 is 65

A square has side length of 8 in. If the area is multiplied by 36, what happens to the side length? HELP PLEASE!!
GaryK [48]

Answer:

The side length is multiplied by 6.

Step-by-step explanation:

The area of a square is A = s². Suppose the side is 8 inches. This means the area is A = 8² = 64.

If you were to multiply by 36, then it becomes 64*36 = 2,304. Since squaring gave the area, it's side length would be found using the reverse operation a square root. Take the square root of 2,304.

√2304 = 48

The side length changed from 8 to 48 which is a scale factor of 6. This means 8 * 6 = 48.

Simplify. (2/5)^4... words to fill in minimum space
Stella [2.4K]
When you have a power to a fraction, you simply take it by the top and then by the bottm.

So, split it into two: (2)^4 and (5)^4

Solve: (2)^4=16
(5)^4=625

So the fraction is: 16/625

Check to see if it reduces: It doesn't. (Odd and even numbers that have no common multiples).

Therefore, that's the answer.
