Ms. peterson wrote the expression below on the chalkboard for her class. she asked the students to write an equivalent expression using no more than one
set of parentheses. 4(3x+5y+2z)+ 3(x-z)• tom wrote 12x+20y+8z • jenna wrote 5 (3x+4y+z)• chris wrote 15x+20y-5zwhich, if any, of the three students wrote an expression that is equivalent to ms. peterson’s expression?

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
