If this a table then the right side would be x and the left would be y. To find the y intercept you would have to find the zeroth term. (85 is the first term) i think the zeroth term might be 65. i subtracted 20 from 85 since that seems to be the pattern for y.
Answer:
∠ QRS = 43°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
4n - 9 + 5n - 18 + 90 = 180, that is
9n + 63 = 180 ( subtract 63 from both sides )
9n = 117 ( divide both sides by 9 )
n = 13
Thus
∠ QRS = 4n - 9 = 4(13) - 9 = 52 - 9 = 43°
∠ RSQ = 4n - 18 = 4(13) - 18 = 65 - 18 = 47°
Answer:
4 is the length
Step-by-step explanation:
14 and 4
14 x 14 + 4 x 4 = 212
14 + 4 = 18
1. Let L=length and W=width
2. L=5w+2
3. The perimeter can be solved as follows:
(5w+2) + (5w+2) + w + w = 114 in
12w + 4 = 114 in
12w = 110
w = 110/12
w = 9.17
L = 47.83
