Pls help 13 points and brainliest for quickest correct answer If X=2 and Y=5, work out the value of 3xsquared +2ysquared

136

Step-by-step explanation:

^2 means exponent of 2 or squared

we're gonna turn x into 2 and y into 5 sense that's what its equal to

when working with variables you multiply x times the number next to it so,

(3 x 2 ^2) +(2 x 5 ^2) will be the actual problem.

3 x 2 = 6

2 x 5 = 10

now sense they're squared it means you have to multiply it by itself

6 x 6 = 36

10 x 10 = 100

so, 100 + 36 = 136

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
