Answer:

277cm²

Step-by-step explanation:

Base = 9x8=72

There are 2 triangles with a bottom edge of 9 and a slant height of 13:

1/2(9)(13)=58.5

There are 2 triangles with a bottom edge of 8 and a slant height of 11:

1/2(8)(11)=44

72+58.5+58.5+44+44=277cm²

How do you explain how to get h(t)=7(t-25)

Nutka1998 [239]

Hey There! :)

To Solve for t.
$h(t)=7(t-25)$
Distribute the brackets.
$h(t)=7*t-7*25$
$h(t)=7t-175$
Subtract 7t from both sides.
$(h(t))-7t=(7t-175)-7t$
$(h(t)-7t=-175$
$h*t-7t=-175$
Factor out variable, t.
$t(h-7)=-175$
Divide both sides by h-7.
$(t(h-7))/h-7=(-175)/h-7$
$t=-175/h-7$

Hope this helps!
