Answer:
37°
Step-by-step explanation:
sum of exterior angles of a polygon is 360°
so, 41+(x+13)+(2x-14)+(3x-22)+(x-3)+38+(x+11)=360
8x+64=360, subtract 64 from both sides
8x=296
x=37°
Answer:
Step-by-step explanation:
54 equals 9 more than a number
So if we do this, we get
54 = x+9
x+9 = 54
54-9=x
54-x = 9
Answer:
x = 1 and x = -1
Step-by-step explanation:
Next time, please separate the equations with a comma or semicolon. Thanks.
We can substitute 4x for y in the quadratic equation x^2 + y^2=17:
x² + (4x)²=17.
Then x² + 16x² = 17, or
17x² = 17, or x² = 1. There are two solutions: x = 1 and x = -1.
Answer: x=14.4
Step-by-step explanation:
Answer:
b 10¹
Step-by-step explanation:
Consider the volume formula:
V = 1/3Bh . . . . B is the base area and h is the height
Replacing h by 10h gives ...
V' = 1/3B(10h) = 10(1/3Bh) = 10V
The volume is multiplied by 10 = 10¹.
