If (7²)x = 1 what is the vaule of x

x=4

Step-by-step explanation:

1 Add 11 to both sides.

2x=7+12x=7+1

2 Simplify  7+17+1  to  88.

2x=82x=8

3 Divide both sides by 22.

x=\frac{8}{2}x=

2

8

4 Simplify  \frac{8}{2}

2

8

  to  44.

x=4x=4

cheek:

1 Let x=4x=4.

2\times 4-1=72×4−1=7

2 Simplify  2\times 42×4  to  88.

8-1=78−1=7

3 Simplify  8-18−1  to  77.

7=7 7=7

(or -3)

x=1/49

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation

Add  1  to both sides of the equation :  

                     49x = 1

Divide both sides of the equation by 49:

                    x = 1/49 = 0.020

Hope this helps

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
