Answer 1

Answer:

Answer:

Solution given:

f(x)=x²

g(x)=x+5

h(x)=4x-6

now

23:

(fog)(x)=f(g(x))=f(x+5)=(x+5)²=x²+10x+25

24:

(gof)(x)=g(f(x))=g(x²)=x²+5

25:

(foh)(x)=f(h(x))=f(4x-6)=(4x-6)²=16x²-48x+36

26:

(hof)(x)=h(f(x))=h(x²)=4x²-6

27;

(goh)(x)=g(h(x))=g(4x-6)=4x-6+5=4x-1

28:

(hog)(x)=h(g(x))=h(x+5)=4(x+5)-6=4x+20-6=4x-14

Really easy seventh grade math can I get this problem answered? Thanks!!

Answers

20/8=x/6
x=15
they are similar so the proportion is the same

x = 15

since the figures are similar then the ratios of corresponding sides are equal

$(x)/(6)$ = $(20)/(8)$ ( cross- multiply )

8x = 6 × 20 = 120 ( divide both sides by 8 )

x = 15
