1. x squared= 16
x= square root of 16
x= =plusminus4
2. t squared=81
t=square root of 81
t=plusminus9
3.r squared-100=0
r squared=100
r = square root of 100
r=plusminus10
4. x squared- 144=0
x squared=144
x=square root of 144
x=plusminus12
5. 2s squared=50
2s squared=50 over 2 ;then cancel 2
s squared=25
s= square root of 25
s=plusminus5
6.4x squared-225=0
4x squared=225
4x squared=225 over 4; then cancel 4
x=square root of 56.25
x=plusminus7.5
7. 3h squared-147=0
3h aquared=147
3h squared=147 over 3; then cancel 3
h=square root of 49
h=plusminus 7
I can only give you these 7 answers because im not really sure of my answer in number 8,9 and 10.
