Solve x2 − 10x = −13.

aev [14]

Answer:

Step-by-step explanation:

First, let's rearrange the given equation into something more recognizable. If we add 13 to both sides, we now have the polynomial $x^{2}-10x+13$ . We can now use the quadratic formula to solve.

Remember that the quadratic formula is

$\frac{-b+/-\sqrt{b^{2}-4ac } }{2a}$

Substitute the numbers from the equation into the formula.

$\frac{-(-10)+/-\sqrt{(-10)^{2}-4(1)(13) } }{2(1)}$

Simplify:

$\frac{10+/-\sqrt{100-52} }{2}$

$\frac{10+/-\sqrt{48} }{2}$

Here, I'm going to assume that there was a mistype in option B because if we divide out the 2 we end up with $5+/-\sqrt{48}$ .

Hope this helps!

What’s the value of x and y

postnew [5]

Answer:

x = 60°

y = 50°

Step-by-step explanation:

Sum of all 3 angles in a triangle = 180

x + 50 + 70 = 180

x + 120 = 180

x = 180 - 120

x = 60

The triangle on the left, also sum of all 3 angles in a triangle = 180

unknown angle = 180 - (50 + 60) = 180 - 110 = 70

y = 180 - (60 + 70) = 180 - 130 = 50
