10x+2y, this is the simplified version
Answer:
∠R = 55.6°
∠Q = 62.2°
∠S = 62.2°
Step-by-step explanation:
total interior angle sum = 180°
2x + 29 + 4x + 9 + 4x + 9 = 180
combine like terms:
10x + 47 = 180
subtract 47 from both sides of the equation:
10x = 133
divide both sides by 10:
x = 13.3
∠R = 2(13.3) + 29 = 55.6°
∠Q = 4(13.3) + 9 = 62.2°
∠S = ∠Q
You cannot factor it any further as it is in its simplest factored form. There is no common factor in either the term (25x^2) or (9y^2) that you can pull out so it cannot be simplified. Hope this helps
We rewrite equations to make them simple or to solve them. Solving algebraic equations often means isolating the variable or rewriting the equation so that one expression is only the variable with a coefficient of 1
Radius
is half of the circle
diameter
is the whole thing inside the circle
since it is a radius, and it is a half of the full circle, we need to double out that number, and multiply by 2.
so here, you said it is 28
take 28, and multiply by 2, if you do every thing correctly, you should get:
56
so then answer would be 56 centimeters.
Hope that this helps you! =)
