Answer:

1/4

Step-by-step explanation:

First,simplify the exponent in the parentheses:

4^-2 x <u>(-1)^0</u> x 4^1

4^-2 x 1 x 4^1

Then simplify the rest:

4^-2 x 1 x 4^1

1/16 x 1 x 4

Then multiply from left to right:

1/16 x 1 x 4

1/16 x 4

1/4

(-1)^0:A number that is raised to the power of 0 will always be 1.

A square and a rectangle have the same perimeter. The square has a side length of 8x units. The rectangle has a length of (10x+8
Elden [556K]
Well we know that the perimeters are equal so:
Psquare = Prectangle

we know perimeter for square is the 4 sides of same lengths added up or 4*s

the perimeter of a rectangle is the then4 sides with 2 being equal added up so 2*L + 2*W

we know that a square side equAls s and it says that s=8x. So:
Psqu = 4 * (8x) (substitute 8x for s)

we know that the rectangle L =10x + 8 and W =10. So
Prect = 2 *(10x + 8) + 2 * (10)

we know :
Prect = Psqu so:
4 * (8x) =2 *(10x + 8) + 2 * (10)
32x = 20x + 16 + 20
12x = 36
x = 3

So if x equals 3 we can sub x in for square perimeter
Psqu = 4 *(8 * 3)
P = 4 * 24
P = 96

we can check this with rectangle perimeter
P = 2 *(10 * 3 + 8) + 2 *10
P = 2 * 38 + 20
P = 96

In the diagram, △ABC≅△DEF. Find the values of x and y.
Scorpion4ik [409]

9514 1404 393

Answer:

  • x = 5
  • y = 20

Step-by-step explanation:

We need x first.

  AB = DE

  12 = 3x -3

  4 = x -1 . . . . . divide by 3

  5 = x

Now, we can find y.

  ∠C = ∠F

  7x +y = 55

  y = 55 -7x = 55 -7(5)

  y = 20

Answer:

19 or m = 19

Step-by-step explanation:

7(13) - 4(13) = m + 20

91 - 52 = m + 20

39 = m + 20

subtract 20 from both sides to get m = 19
