What would the answer be (2x - 6y ) ( x + y )

Your answer would be 128!

(17/8, -1/8) or if you want it in decimals  (2.125, -0.125)2x-6y=5                    x+y=2      y=2-x2x-6(2-x)=52x-12+6=58x-12=58x=17x=17/8(17/8)+y=2   You plug in the x-value to find the y-value now y=2-17/8y=-1/8

there is no grid

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
