Helppppsolve for X and then find the measure of

Mathematics
1 answer:
miskamm [114]1 year ago

Here in this question, we are to solve for x and get the measure of Angle A

Mathematically,

∠A = ∠B

The reason for this is because both are corresponding angles and corresponding angles are equal.

Since they are equal in value, we can equate the given expressions for each of the two angles

Thus;

7x + 40 = 3x + 112

Let us collect like terms

7x-3x = 112 - 40

4x = 72

x = 72/4

x = 18

But the question asks to get the value of ∠A

From the questionn, we are told that ∠A = 7x + 40

To get the value of ∠A, we need to substitute x

∠A = 7(18) + 40

∠A = 126 + 40

∠A = 166

∠A = 166 and x = 18

Simplify the expression below:
kifflom [539]

Answer:

C. -7x^2 - 28

Step-by-step explanation:

Firstly simplify the bracket before doing anything;

4x(3x - 7) = 12x^2 - 28x

then go back to the question and substitute the expression(12x^2 - 28x) on the bracket and then work out the question;

12x^2 - 28x -19x^2...then group the values with the same exponent of x,

(12x^2 - 19x^2) - 28x

; -7x^2 - 28x

What is the extraneous solution?
8_murik_8 [283]
<h3>Answer:</h3>

  x = 1

<h3>Step-by-step explanation:</h3>

<em>The only solution is an extraneous solution</em>, which is to say the equation has no solution.

The rational expression reduces to -1 (for x≠1), which makes the equation ...

  1 = 1/x

The only solution to this is x=1, which is specifically disallowed.

___

If you subtract the right side, the equation becomes ...

  ((-x+1)(x) +2(x)(x -1) -(x -1))/(x -1) = 0

  (-x^2 +x +2x^2 -2x -x +1)/(x -1) = 0 . . . . eliminate parentheses in the numerator

  (x^2 -2x +1)/(x -1) = 0 . . . . . . . . . . . . . . . collect terms

  (x -1)^2/(x -1) = 0 . . . . . . . . . . . . . . . . . . . factor

This is undefined for the only value of x that could possibly be a solution, x=1.
