Answer:
146 in
12ft 2in
Step-by-step explanation:
4ft 9 = 4*12+9=48+9=57
3ft 10 = 3*12+10=36+10=46
3ft 7 = 3*12+7=36+7=43
57+46+43=146
146/12 = 12ft remainder 2
12ft 2in
To solve this multiply through by the LCM of 4 and 6, which is 12:-
12 * x/4 - 12 * x/6 = 1*12
3x - 2x = 12
x = 12 answer
I think it is 5/6 because you would have to choose a small amount
450 miles/15 gallons is reduced to 30 miles/1 gallon
Answer:
10x + 12 and 6x² + 11x - 7
Step-by-step explanation:
The perimeter (P) of a rectangle is calculated as
P = 2l + 2w ( l is length and w is width )
= 2(2x - 1) + 2(3x + 7) ← distribute parenthesis
= 4x - 2 + 6x + 14 ← collect like terms
= 10x + 12
--------------------------------------------------
The area (A) of a rectangle is calculated as
A = lw
= (2x - 1)(3x + 7) ← expand using FOIL
= 6x² + 14x - 3x - 7 ← collect like terms
= 6x² + 11x - 7
