Answer:
width = w
length= 3w+1
perimeter= 5(3w+1) -45
perimeter = 2(l+b)
5(3w+1) -45 = 2{(3w+1)+w}
15w - 40 = 8w+2
6w = 42
w =7
therefore width = <u>7</u>
length= 3w+1 = <u>22</u>
perimeter= <u>65</u>
Step-by-step explanation:
A (103)(109)
=103*109
=(10*10*10)*(10*10*10*10*10*10*10*10*10)
=10*10*10*10*10*10*10*10*10*10*10*10
=1012
=1000000000000

Answer:
Step-by-step explanation:
It when you do this tan that equals 4:12
Answer:
39.9
Step-by-step explanation:
A good trick to remember is SOH CAH TOA.
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
Here, we're given an angle and the opposite side, and we want to find the adjacent side. So we need to use tangent.
tan 31° = 24 / x
x = 24 / tan 31°
x ≈ 39.9
You can either make a table using any numbers you would like (I would suggest -5 to 5) and then graphing the rule
ex. (7/2)(-5)-2 = -19.5 (I multiplied (7/2) by -5 and then subtracted 2)
Or you can put the rule in a graphing calculator and check the points from there
