The picture's length and width are 18 and 5. You subtract 2 instead of 1 because you are subtracting 1 on both sides of the frame.
The area of the picture is 90, and the area of the whole thing, picture and picture frame, is 20*7=140.
So, to find the area of just the picture frame, you subtract 90 from 140 to get 50in^2, which is your last answer choice.
Answer:
A
Step-by-step explanation:
Since there are 28 days in a regular February and 365 days in a total year, the probability that a random person is born in February is 28/365. This means that the probability that they were NOT born in February is 337/365, or answer choice A. Hope this helps!
Answer:
Step-by-step explanation:
(11,13) (8,18)
slope = y₂ - y₁/x₂-x₁
= 18- 13 / 8-11
= 5 / - 3
= -5/3
Answer:
Step-by-step explanation:
4(2y -8) + y = 13
8y - 32 + y = 13
9y - 32 = 13
9y = 45
y = 5
x = 2(5) - 8
x = 10 - 8
x = 2
(2, 5)
Answer:
400
Step-by-step explanation:
4 * 1 = 4
4 * 2 = 8
4 * 3 = 12
4 * 4 = 16
4 * 5 = 20
4 * 6 = 24
................
4 * 100= 400
