Answer:

You can combine like terms when they have the same variable, same category, or same coefficient. You CANNOT combine like terms when they have none of the attributes listed above. For example, you can combine 7x and 20x, just like you can combine 3 and 4, but you can't combine 3x & 5(x^2), or 9x and 73.

On a unit circle, the vertical distance from the x-axis to a point on the perimeter of the circle is twice the horizontal

tia_tia [17]

Answer:

(2/5)√5 ≈ 0.894427

Step-by-step explanation:

You require the y-coordinate of the point that satisfies two equations:

x^2 +y^2 = 1

y = 2x

Substituting for x, we have ...

(y/2)^2 +y^2 = 1

y^2(5/4) = 1

y^2 = 4/5

y = (2/5)√5 ≈ 0.894427

The sine of the angle is (2/5)√5 ≈ 0.894427.

How do you find the width of a rectangle when the perimeter is given?

ololo11 [35]

Usually you are given more information about the rectangle such as distance of length in terms of width.

You know that the formula for perimeter is

P=2(l+w)

Substitute p and the other values to find width.

Hope I helped :)

How do I solve for n and m using special right triangle rules.

kenny6666 [7]

Answer:

Because the triangle is a 45-45-90 triangle, the n and m should be the same lengths. For these types of triangles, the hypotenuse is $x\sqrt{2}$ and the side lengths are x. Because we are given the length of the hypotenuse, we need to find the x-value. The equation should be 6= $x\sqrt{2}$ . Simplify to get x= $3\sqrt{2}$ . So, the length of n and m should both be $3\sqrt{2}$ .
