Icompletely don’t understand how to even start.

(5x - 2)(-2x + 4) = -10x^2 + 20x + 4x - 8  

= -10x^2 + 24x - 8  

Option 1 is not equivalent to this.

I believe that it would be A.

Step-by-step explanation:

I think its A because if you take 5x times -2x to get -10x then do 5x times 4which is 20x, then you do -2 times -2x to get 4x then 2 times 4 to get 8 so it would be -10x+20x+4x-8

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.
