Solve the exponential equation: 4x - 2 = 2x

svetlana [45]

Answer:

x= 1

Step-by-step explanation:

Solve

Let's solve your equation step-by-step.

4x−2=2x

Step 1: Subtract 2x from both sides.

4x−2−2x=2x−2x

2x−2=0

Step 2: Add 2 to both sides.

2x−2+2=0+2

2x=2

Step 3: Divide both sides by 2.

x=1

Given: ABCD is a trapezoid with AB || DC. If m∠A = 125 and m∠B = 99, find m∠C/

Pavlova-9 [17]

Answer:

The measure of angle C is $81\°$

Step-by-step explanation:

we know that

If AB || DC

then

$m$ -----> supplementary angles by consecutive interior angles

and remember that the sum of the interior angles in a trapezoid is equal to 360 degrees

$m$

step 1

Find the measure of angle D

$m$

substitute the measure of angle A

$125\°+m$

$m$

step 2

Find the measure of angle C

$m$

substitute the values

$125\°+99\°+m$

$m$
