Answer:
a=120
b=240
Step-by-step explanation:
if x=12
a=5×2×2×2(x-5)
5×2=10×2×2=40
40(x-5) 40x-200
200=40×\40x=5
b=2×10×12=240
a=120
b=240
Your answer would be be subtract 3
hope it helps
The answer would be D. (11,14),(8,18)
To find the answer you need to find an equal slope.
To find the slope you need to do y2-y1/x2-x1
Y2 is 18, y1 is 13, x2 is 8, and x1 is 11
18-13/8-11
5/-3=
-5/3
Answer:
9, 11 and 19
Step-by-step explanation:
the first two integers I've picked are 19 and 9 because it gives a range of 10 and is less than 25
the range is the bigger number - smaller number
19 - 9 = 10
to find the third number we are given mean = 13

the third number = x

multiply both sides by 3 to get rid of the fraction


subtract both sides by 28


the third number is 11
the three integers are 9, 11 and 19
there are two other possible answers:
8, 13 and 18
7, 15 and 17
B) square root of 3
Repeating decimals are rational, surprisingly enough.
Fractions are rational.
The square root of 16 is 4, which is rational.
