(a ± b)² = a² ± 2ab + b² . . . . . . . (signs match)

The middle term is twice the product of the roots of the other two terms. This tells you the terms of the binomial are the square roots of the end terms.

The sign in the binomial will match the sign of the "2ab" term. The order of terms in the binomial doesn't matter. (a±b)² = (b±a)² when signs match.

WZ and XR are diameters what is thr measure of ZWX?
castortr0y [4]

Answer:

mZWX = 214°

Step-by-step explanation:

In a circle C, XR and WZ are two diameters.

∠ XCW = 34° and ∠ YCZ = 86°

We have to find the measure of arc ZWX

Since ∠XCW + ∠XCY + ∠YCZ = 180° [ angles on a straight line ]

34° + ∠XCY + 86° = 180°

120° + ∠XCY = 180°

∠XCY = 180 - 120 = 60°

Now arc ZWX = 360° - (∠XCY + ∠ YCZ)

                       = 360° - (60° + 86°)

                       = 360° - 146°

                       = 214°

Therefore answer is arc ZWX = 214°

Solve the literal equation for x.<br> y=5x-rx-5
Alchen [17]

Answer:

x = \frac{y+5}{(5-r)}

Step-by-step explanation:

Given the literal equation, y = 5x - rx - 5,

In order to solve for x, start by adding 5 on both sides of the equation:

y + 5 = 5x - rx - 5 + 5

y + 5 = 5x - rx

Next, factor out x from the right-hand side of the equation:

y + 5 = x(5 - r)

Finally, divide both sides by (5 - r) to isolate x:

\frac{y+5}{(5-r)} =  \frac{x(5 - r)}{(5-r)}

\frac{y+5}{(5-r)} =  x
