C because you have to do 50÷2=25 and 40÷2=20 and 20-25=5
Factorising quadratic expressions
Multiply these brackets to remind yourself how to factorise.
<span><span>( x + 2 ) ( x + 5 ) = x2 + 7x + 10</span><span>( x + 2 ) ( x + 3 ) = x2 + 5x + 6</span><span>( x - 3 ) ( x - 5 ) = x 2 - 8x + 15</span><span>( x + 6 ) ( x - 5 ) = x2 + x - 30</span><span>( x - 6 ) ( x + 5 ) = x2 - x - 30</span></span>
X = third angle
82° + 62° + x = 180°
144° + x = 180°
x = 36°
Answer:
Step-by-step explanation:
<u>The difference of −2d and −3d is equal to the difference of 1/6 and 1/3</u>
- -2d - (-3d) = 1/6 - 1/3
- -2d + 3d = 1/6 - 2/6
- d = -1/6
If i am correctthe answer is
y= 70
z=1
