Answer:

x • (2x + 7)

Step-by-step explanation:

2.1     Pull out like factors :

  4 - 2x  =   -2 • (x - 2)

Equation at the end of step  2  :

 ((8 • (x2)) -  5x) +  -6x • (x - 2)

Step  3  :

Equation at the end of step  3  :

 (23x2 -  5x) +  -6x • (x - 2)

Step  4  :

Step  5  :

Pulling out like terms :

5.1     Pull out like factors :

  2x2 + 7x  =   x • (2x + 7)

Answer:

Step-by-step explanation:

8x² - 5x + 3x(4 - 2x) =8x² - 5x + 3x*4 - 3x*2x

= 8x² - 5x + 12x - 6x²

Now add the like terms

= 8x² - 6x² - 5x + 12x

= 2x² + 7x

Which statement is an example of the symmetric property of congruence?
BabaBlast [244]
The <u>correct answer</u> is:

\text{D) If }EFG \cong HJK, \text{ then } HJK \cong EFG.

Explanation:

The symmetric property states that if two quantities are equal (or congruent), you can "flip" them around the equals sign (or congruence sign).  

This means since EFG is congruent to HJK, then HJK is congruent to EFG.

I need help for this question please!!!!
Arisa [49]

Answer:

a. 35 degrees

b. 145 degrees

Step-by-step explanation:

a. Since the two base angles of this triangle are congruent, we can conclude that the triangle is <em>isosceles, </em>which means that the two base angles and sides are congruent.

Now, knowing that information, we can subtract 110 from 180 (the sum of all interior angles in a triangle) and we get 70. But this isn't our answer. This is the sum of both base angles. Since the base angles are congruent, we can divide the 70 by 2 to get the measure of ONE base angle, which is 35 degrees.

b. There are two approaches to solve this problem. I have worked both out.

1) We can use the Exterior Angle Theorem, which states that the sum of the interior angles is equal to the exterior angle. We can add 110 to 35, so we get 145 degrees as the measure of <1.

2) The second approach is supplementary angles. Since we see that one of the base angles and <1 is on the same line, we can subtract 35 from 180 to find the measure of <1 to get 145 degrees.

Either way you use, you get the correct answer. Hope this helped!

Step-by-step explanation:
with the information given, we can express the equation:

where is the unknown number?
to clear for first we multiply the equation by 2, to eliminate the fraction:

moving all terms with to the left:

and adding +16 to each side:

and finally, dividing by 3

the number is 4.
