Find the value of 2asquared + 5bsquared

Hello from MrBillDoesMath!

 4a^2 + 25b^2

Discussion.  First, I write the square of a number using the notation "^" which appear on the 6 key of the keyboard. As 3 times 3, or 3 squared, is 9, this becomes 3^2 = 9.

I interpreted you question as asking for the value of

(2a)^2 + (5b) ^ 2 =  (2a)(2a) + (5b)(5b) = 4a^2 + 25b^2.

Regards, MrB.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
