9m-28=2m
9m-28-2m=2m-2m
(9m-2m)-28=0
7m-28=0
7m-28+28=0+28
7m=28
(7m)/7 = 28/7
m=4

PLEASE HELP - Find the area of a regular octagon with a side length of 5 cm. Round to the nearest tenth. (Please explain in full
Vinil7 [7]

Answer: 482.8 sq cm

Step-by-step explanation:

The octagon is 8 isosceles triangles.  Each has common side r and base 10.  The central angle is 360/8 = 45°.  By the Law of cosines,

10² = r² + r² - 2 r² cos 45° = 2r²(1 - √2/2) = r²(2-√2)

r² = 100/(2-√2)

The area of a triangle with sides a,b and included angle C is (1/2)ab sin C. Our 8 octagon isosceles triangles each have sides r and r and included angle 45° so our total area, 8 triangles, is

A = 8(1/2) r² sin 45° = (400/(2-√2)) (√2/2) × (2+√2)/(2+√2) = 200(1+√2)

A ≈482.84271

Answer: 482.8 sq cm

just olya [345]

Answer: -3/5

Step-by-step explanation: -3^3 is 27 and 5^3 is 125. So when you find the cube root of this equation you just simplify it to that.

Each product is in the form ax2 + bx + c. Which of the following describes the relationship between b and c?
KIM [24]

Answer:

The correct answer is c. c is the square of half of b.

Step-by-step explanation:

In all perfect square trinomials, half of the middle number squared gives you the constant. See the example below for proof.

(x + 4)^2

(x + 4)(x + 4)

x^2 + 4x + 4x + 16

x^2 + 8x + 16

You'll notice if you take the middle term (8), cut it in half (4) and then square it (16), the result is the constant.
