Ie 32^2 - 4ac=0 so ac=256 and a+c=130
So, that means:2 equations ac=256 a+c=130 ie c=130-a
So,a(130-a)=256 so 130a -a^2=256 ie a^2-130a +256=0 (a-2)(a-128)=0
Finally,giving a= 2 or a=128 so, a=2 c=128 or a=128 c=2
Since, a>c , a=128 and c=2 ie (128,2)
You would round 762 to 800, then you would round 332 to 300. You would take those 2 numbers and put them in the questions and it should look like this:
800-300, then you would subtract
Good luck!
46? Since we got 7*3+5*5 and that is 21+25=46.
X = -21
Step 1: Subtract 6 from both sides -1/3x = -7
Step 2: Divide -1/3 from both sides x = -21
