Answer: x=14
Step-by-step explanation: The total is 180 degrees. The right angle is 90, the given angle is 76, so x is 14.
<u><em>Answer:</em></u>
Andrew's height is 
meters
<em><u>Explanation:</u></em>
We know that John's height is 
meters
<u>We are given that:</u>
John is 
meters shorter than Paul
<u>This means that:</u>
Paul's height = John's height +
Paul's height = 
meter
<u>We are given that:</u>
Paul is 0.25 meters taller than Andrew
<u>This means that:</u>
Andrew's height = Paul's height - 0.25
Andrew's height = 
meters
Hope this helps :)
Answer:
1) (2x + 2)(x + 2)
2) 2(x + 1)(x - 1)
3) (x^2 + 3)(x^2 - 3)
4) 2x(x + 5)(x - 2)
5) (5x + 2y)(5x - 2y)
Step-by-step explanation:
1)
2x^2 + 6x + 4
= 2x^2 + 4x + 2x + 4
= 2x(x + 2) + 2(x + 2)
= (2x + 2)(x + 2)
2)
2x^2 - 2
= 2(x^ 2 - 1) (The difference of two squares)
= 2(x + 1)(x - 1)
3)
x^4 - 9 (The difference of two squares)
=(x^2 + 3)(x^2 - 3)
4)
2x^3 + 6x^2 - 20x
= 2x(x^2 + 3x - 10)
= 2x(x + 5)(x - 2)
5)
25x^2 - 4y^2 (The difference of two squares)
= (5x + 2y)(5x - 2y)
A. A= 4
b. b= 5.6
c. c=4
d. e= 3.2

Answer:
-11
Step-by-step explanation:
DeYanna's cards are ...
black: 2, 4, for a total value of 2+4 = 6
red: 7, 10, for a total value of -(7+10) = -17
Then the total value of DeYanna's cards is ...
6-17 = -11
