Answer:
you +1 on each side
Step-by-step explanation:
a is 30-1=7
b is 32=8
to get from "a" to "b" you simply add one on both sides
32 - 1 = 7
+ 1 +1
------------------
32=8
Answer:
8 sides
Step-by-step explanation:
let x be the exterior angle then 3x is the interior angle
interior angle + exterior angle = 180° , then
x + 3x = 180
4x = 180 ( divide both sides by 4 )
x = 45
the sum of the exterior angles of a polygon = 360°
since the polygon is regular with each exterior angle = 45°, then
number of sides = 360° ÷ 45° = 8
Answer:
3789
Step-by-step explanation:
We want to get x by itself
First we will multiply both sides by 6 to cancel out the 6 on the left
5x = 120
We then divide by 5 on both sides to get x by itself
x = 24
Answer:
The answer is -343.
Step-by-step explanation:
If a term doesn't have an exponent, it's considered that the exponent is 1 (so basically, (-7)² x (-7)^1.
Multiply the terms with the same base (by adding the exponents - (-7)²+1<- (as the exponential value) (couldn't find the sign so sorry.)
Add the numbers: (-7)³
A negative base raised to an odd power equals a negative: -7³
Write the problem out: -(7 x 7 x 7).
Multiply: -343
