Convert decimal to fraction
a^2+(21/10)^2=2.9
Use exponent rules
a^2+441/100=2.9
Move constant to the right
a^2=2.9-441/100
Calculate
a^2=-151/100
This equation has no solution.

you can use the explanation below to help find the other 6 problems
Step-by-step explanation:
1) 4(5+6) - 15 = 4 * 11 - 15 = 44 - 15 = 29
2) 8(2+4) + 16 = 8 * 6 + 16 = 48 + 16 = 64
