All work must be shown 4. Harold works at a state park. He needs to seal the redwood deck at the information center to
protect the wood. He measures the deck and finds that it is a kite with diagonals 40 feet and 70 feet.
a) What is the area of the deck? b) If each gallon of sealant covers 400 square feet, how many
gallons of sealant are needed? c) If the sealant only lasts six months, then how many gallons of
sealant are needed to protect the deck for the next three years?

a

step-by-step explanation:

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
