2x=3 or x=3/2 i think thats right
So the equation would be “a squared +4 squared=8 squared.” Then you would square 4 which would be 16 and 8 which would be 64. Now the equation is a squared+ 16=64 the rest is basic algebra. Subtract 16 from 64 which is 48. Now you have a squared= 48. You get the square root of both sides so now you have the square root of a is 6.9. I’m pretty sure that’s how you do it. I apologize if I’m incorrect.
Xints are where y=0
0=x^2+4x-12
0=(x-2)(x+6)
x-2=0
x=2
x+6=0
x=-6
(x,y)
xints are
(2,0) and (-6,0)
2x + 7y + 3x - 4y
Collect all the like terms:
2x + 3x = 5x
7y - 4y = 3y
And you end up with 5x + 3y as your final answer :)
72 is 50 or above so you round it up.
<u />572 to the nearest hundred is <u>600</u>
