Answer:
See below
Step-by-step explanation:
4 more than 3: 3 + 4 = 7
5 out of 9: 5/9
the sum of 6 and 8: 6 + 8 = 14
10 less than 14: 14 - 10 = 4
the product of 3 and 4: 3 * 4 = 12
the ratio of 2 to 3: 2/3
10 decreased by 8: 10 - 8 = 2
the quotient of 23 and 25: 23/23
3 increased by 33: 3 + 33 = 36
50% of 32: 50% * 32 = 0.5 * 32 = 16
If there are 15 boards there are 14 gaps in-between.
But first, 15 boards each 9 and 1/4th inches so you get a total of 138 inches and 3/4th
If you subtract that from 144 you get 5 inches and 1/4th. The remaining amount is the total of all of the distance from the spacing.
Then you divide that by 14 (number of gaps/spacing in-between.)
So you get .375 inches. (3/8)
So width of the spacing between each board is 3/8ths of a inch
Answer:
b) -10
Step-by-step explanation:
x^2 + 3x + k = (x - 2)(x - a)
(x - 2)(x - a) = x^2 - 2x - ax + 2a = x^2 + [-2 - a)x] + 2a
-2 - a = 3
2a = k
a = -5
k = 2(-5) = -10
Answer: b) -10
