Solve the equation for a. a^2 + 10^2 solve the equation for a. a2 + 102 =12^2

i'm not entirely sure

step-by-step explanation:

if you ask home depot or lowe's they might be able to you out

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

113.42

i hope that is right.
