A)
x 0 1 2 3 4
y 5 10 15. 20. 25
b) x 0 1 2 3. 4
y 1. 10. 37. 82. 145
Answer:
Step-by-step explanation:
×7 = 
Dimensions of rectangle = 12 + x and 14 + x
(12 + x) (14 + x) = 288
x^2 + 26x + 168 = 288
x^2 + 26x - 120 = 0
(x + 30) (x - 4) = 0
x=-30, x =4
since 4 is positive
the dimensions increased by 4 feet
check the answer
12+4 = 16
14 +4 = 18
18*16 =288
<span>223 degrees
To find the missing angle, you first have to add up all the numbers you know. So 125, 132, 148, 124, 122, 106 and 100 degrees add up to 857 degrees.
We know that the total degrees of an octagon is 1080 degrees, so to find the last number, we would simply do 1080 minus 857 which is 223 degrees.
