Answer:
3240°
Explanation:
The formula for calculating the sum of the interior angles of a polygon is (n-2)x180 where n refers to the number of sides. Because we know that the polygon has 20 sides, the equation would be (20-2)x180. The answer would be 3240°.
I'm not familiar with the use of square brackets/parentheses
I'm assuming it wants (3x15) times (2x10) then that times'd by 2x.
150-2x(900)
150-1800x doesn't make sense however. Can you rephrase the question?
Answer:
16y -25
Step-by-step explanation:
7-4[3-(4y-5)] = 7 -4(3 -4y +5) = 7 -4(-4y +8)
= 7 + 16y -32
= 16y -25
