Answer:
In the first one you are missing (x - 3) so it will be 4(x - 3) and if you factor it out it will be 4x - 12
In the second one you are missing a (x -5)which means 9x(x -5) or when you factor it out it will be 9x^2 - 45x
Step-by-step explanation:
3x^2 -23x + 40 = (3x - 8) (x - 5)
3x^2 -17x + 24 = (3x -8) ( x - 3)
To answer this you will combine both fractions together to get a total. The denominators are not the same so you will need to create equivalent fractions for both with a common denominator. The denominator is like the units, and to be able to add them they must be the same.
2/5 + 3/7
2/5 = 14/35 and 3/7 = 15/35
14/35 + 15/35 = 29/35
29/35 of the garden are these 2 flowers.
Answer:
j=38
Step-by-step explanation:
j/-2 +7=-12, subtract 7 from both sides of the equation and you get j/-2 = -19, then you multiply j/-2 by -2/1 and multiply -19 by -2/1 to get j= 38
Answer:
Step-by-step explanation: 40% 132/330=0.4 and 0.4 as a percent is 40%
Answer: 10%
Step-by-step explanation:
Let the sale tax = $x
Cost price (CP) of the surfboard = $920
Sale tax with cost price of the surfboard = $1,012
Therefore the sale tax ($x) = $1,012 - $920
=$92
Therefore the sale tax percentage = ⁹²/₉₂₀ x 100
= 10%
