Answer:
x=5, -1
Step-by-step explanation:
set the equation equal to 0: 2x^2-8x-10=0
divide both sides by 2 to get x^2-4x-5=0
next factor your new equation to get (x+1)(x-5)
set those equal to zero
now you have x+1=0 and x-5=0
finally, solve for x by subtracting 1 and adding 5
now you have your answer x= 5 and -1
First, you should list the factors of 12. Keep going until you see a number that isn't a multiple of 4.
1 and 12
2 and 6
3 and 4
2, 6, and 3 are all factors of 12 and none of them are multiples of 4.
Sylvia is correct. This is because the sum of angles in a triangle is 180° and a triangle has 3 angles. If it had 2 right angles (90° each) it would already equal 180° and that's not possible because a thrid angle has to exist.
Hope I helped!
