Savannah made two posters. The second poster was 3 times larger than the first. If the first poster was 78 square inches, how large were the posters altogether?

312  square inches

Step-by-step explanation:

Given: The first poster was 78 square inches.

Also, The second poster was 3 times larger than the first.

The area of second poster =  3 x (First poster)

= 3 x (78) square inches

= 234  square inches

The area of both posters = Area of first poster + Area of second poster

= (78+234) square inches

= 312  square inches

Hence, the posters were 312  square inches large altogether.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

step-by-step explanation:

its 512 because parenthesis and to the 2nd power is 512 so it will be 512
