Answer:
72 sides
Step-by-step explanation:
The sum of the angles of a polygon with n sides is (n−2) × 180
Since the polygon is regular, we can divide by the number of sides to find the measure of each angle (n−2) × 180 / n
Each angle is equal to 175
(n−2) × 180 / n = 175
Multiply each side by n
(n-2)180 = 175n
Distribute
180n -360 = 175n
Subtract 180n from each side
180n-180n-360 = 175n-180n
-360 = -5n
Divide each side by -5
-360/-5 =-5n/-5
72 = n
There are 72 sides
Answer: 7
Step-by-step explanation:
just use a comparison
3/12 = x/28
1/4 = x/28
x = 7
The height would be 108 inches. the base would be 156 inches. I figured this bc the 1/4 is half of 1/2 so if 1/4 is 6inches 1/2 would be 12 inches
Step-by-step explanation:
15. If f(x) = 20x, adding a $10 fee for cleaning would be
g(x) = 20x + 10
The graph of g(x) is shifted 10 units up from the graph of f(x).
16. f(x) = 2x + 1
g(x) = (2x + 1) + 5
h(x) = 3f(2x + 1)
g(x) shifted f(x) 5 units to the right.
h(x) is 3 times steeper than f(x).
If this is the correct answer, then please give it the brainliest.
Foil is just like distributive meathod rememebering meathood
so foil is
First
Outer
Inner
Last
so if you had
(a+b)(c+d)
you would do
First
a times c
Outer
a times d
Inner
b times c
Last
b times d so
we have
(b-3)(b+9)
FIRST
b times b=b^2
Outer
b times 9=9b
Inner
-3 times b=-3b
Last=-3 times 9=-27
add
b^2+9b-3b-27
add like terms
b^2+6b-27
answer is A
