Answer:
√11
Step-by-step explanation:
4 = x^2 -7
Add 7 to both sides
11 = x^2
Square root both sides
√11 = x
x= 3.31 or (square root) of 11
0.56
it's basically the number closest to 50. Don't get tricked by the 0.05 because that's only 5% not 50%
4+2+1=7
49p/7=7p
4units:2units:1unit
4 times 7p=28p
2 times 7p=14p
1 times 7p=7p
divided it is
28p:14p:7p
