Answer:

The answer to the expression is 16.

Step-by-step explanation:

So, when c = -7, first plug in -7 to every c variable in the expression.

(-7)^{2} + 4(-7) -5\\

Now simplify:

49 - 28 - 5

16

When c = -7, the expression evaluates to 16.

nikdorinn [45]

Answer:

the triangle above is an isoceles triangle

therefore the base angles are equal

So we have:

2x = 180-38

2x = 142

X = 71°

Finding the roots (zeros)
GenaCL600 [577]

Answer:

1.5 + 1.3228756555323i

1.5 - 1.3228756555323i

Step-by-step explanation:

y = ax^2 + bx + c

a = 1, b = -3, c = 4

Using the quadractic formula:

\frac{-b±\sqrt{b^2-4ac} }{2a} \\\\= \frac{3±\sqrt{9-4(1)(4)}}{2(1)}\\\\= \frac{3±2.64i}{2}\\\\= 1.5 ±  1.32

Note: Kindly ignore the A in the above solution ^

Hence, there is no real solution. It has complex roots.

Aniii geometry . solve the equation 4x-6=34
prohojiy [21]
(1) You can see that the 6 is being added to both sides.

You are trying to make both sides equal by adding 6, so it would be the Addition Property of Equality. 

(2) 4 is being divided into both sides. 

It would be the Division Property of Inequality. (you are dividing by 4 to make both sides equal)

"B" is the answer.

I hope this helps!
