Answer:
-a^2 + -4a + 3a + 12
Step-by-step explanation:
FOIL
First terms: -a x a = -a^2
Outside terms: -a x 4 = -4a
Inside terms: 3 x a = 3a
Last terms: 3 x 4 = 12
well, Marcus and Ben are both 5 feet tall and a little bit more, Marcus is 19/24 more and Ben is 9/16 more, so the 5's in the fraction are the same, so which one is larger, 19/24 or 9/16?
we can simply put both fractions with the same denominator, by <u>multiplying one by the other's denominator</u>, so let's proceed,

Convert 3 yards to inches.
1 yard = 36 inches
3 * 36 = 108
Now subtract this from Jason's jump:
108 - 98 = 10
So Doug's jump was 10 inches longer than Jason's jump.
Answer:
1.5 million
Step-by-step explanation:
To find this you need to find 60% of the 2.5 million people. To do this, multiply 2.5 million by .6, which is 60% in decimal form, and then you'd get 1.5 million.
It would be 5 months because if you do 75 + 20x = 35x
15x = 75
----- ------
15 15
x = 5
