Answer:

-3 plus/minus square root 17 over 4

Step-by-step explanation:

2x squared = -3x + 1 is the same as 2x squared + 3x -1

a=2 b=3 c=-1

sub those into the formula and you get -3 plus/minus square root of 9 + 8 over 2×2

and then you simplify

The hypotenuse of the right triangle is 5y inches long. The lengths of the legs are x + 8 and x + 3 inches. If the perimeter of
Nata [24]

Answer:

25

Step-by-step explanation:

The perimeter of triangle is equal to the sum of all sides of triangle

then:

5y + (x+8) + (x+3) = 60

5y + 2x +11 = 60

5y +2x = 49  ..............................................................(1)

the hypotenuse - shorter leg = 10

hint (  shorter leg ) = x+3

then

5y - (x + 3 ) = 10

5y - x - 3 = 10

5y - x = 13               .................................................... (2)

from 1 and 2

5y +2x = 49  .................................................................. (3)

5y - x = 13 (multiply both sides by 2 )

10y - 2x = 26 ..................................................................(4)

by sum 3 and 4

15y = 75

then y = 75/15 = 5

then hypotenuse = 5y = 5 x 5 = 25

Given (x – 7)^2 = 36, select the values of x. x = 13 x = 1 x = –29 x = 42
ElenaW [278]

Answer:

We know the square root of 36 is 6.

As a result, the total value inside the bracket should give us 6.

Thus, 13 - 7 does gives us 6.

So, x = 13

Or

(x – 7)^2 = 36,

Square root both sides to get rid of the square symbol

Now:

(x - 7) = 6

+7 both sides

x= 13

Hope this helps!
