Error: They subtracted 9x from both sides when they should have subtracted 12. You can’t subtract unlike terms
Correct: x=-5/16
Subtract 12 from both sides to get -5 on the left and add 7x and 9x to get 16x. Divide both sides by 16 to isolate x.
Arranged in descending order means the terms are arranged in the order of the exponent, from the largest to the smallest. the exponent is the little number up right to y,
3y^4+6y^3+2Y^2-5y
so the third term is 2y^2
Answer:
The measure of the interior angle C is
.
Step-by-step explanation:
Sum of angles in a polygon = (n - 2) x 180
where n is the number of sides of the polygon.
For a hexagon, n = 6. So that;
Sum of angles in a hexagon = (6 - 2) x 180
= 4 x 180
= 
Sum of angles in a hexagon = 
⇒ 3x + 15 + 2x + 30 + 5x + 10 + 2x + 55 + 2x + 60 + x - 35 = 
15x + 135 = 
15x =
- 135
15x = 585
x = 
= 
But,
C = 2x + 30
= 2(39) + 30
= 78 + 30
= 
The measure of the interior angle C is
.
Answer:
the first option = 437.4 sq.ft
Step-by-step explanation:
the formula of an are of circle =
A = (pie) (radius) ^2
so fill it, (3.142 × 11.8)^2
and you will got the answer = 437.44
and round it to nearest tenth = 437.4
done!
