4(1.75y−3.5)+1.25y
. First multiply through with 4 the numbers in the parentheses.
7y➖ 14 ➕ 1.25y
add 1.25y to 7y
That will be 8.25y
So the answer will be 8.25y ➖ 14
#9
99 cent for 100 paper
4.29 for 500 paper
multiply 100 and 5=500
so now multiply .99 and 5=4.95
the better deal would be $4.29 for 500 paper
x³ - x² +4x -10 = 0 (next time fix your mismatched parenthesis)
