Answer: Use the given information to create equations to help solve the problem.

H= 4+ 4B

A=24 square feet

Know that the area of a triangle formula is 1/2 x b x h.

A=1/2 x b x h

Plug in the known values and solve for the base.

24= .5 x B x (4+4B)

48=B(4+4B)

48=4B+4B^2

12= B + B^2

0=B^2 + B -12

0=(B+4)(B-3)

B= -4, 3

This solution gives us two answers, so plug both into the formula to find the correct answer.

24=.5 x -4 x (4+4(-4))

48= -4 x (-12)

48=48

24= .5 x 3 x (4+4(3))

48= 3 x (4+12)

48= 3(16)

48=48

It looks like both work, so either answer is correct.

MIDDLE SCHOOL

A square has an area of 36cm2. What is the perimeter

What times what = 36 like two of the same numbers. then multiply that number by 4 for the number of sides and u get the perimiter. (sry if confusing so ill explain that 6×6=36)

Square root of 36 =6. Squares have all same side lengths

COLLEGE

Ralph sold brownies for $0.20 a piece in order to buy baseball cards. If the cards cost $0.36 per pack, and Ralph had no money left over after buying them, what is the least number of brownies he must have sold?

Nine brownies because he could buy 5 packs of baseball cards with $1.80 and sell 9 brownies to get $1.80
