Answer get 6 4 feet piece and you can get
and 8 3 feet pieces
its A.
Step-by-step explanation:
its B
Well there’s 180° in one triangle. a right angle is 90°. 2x+3x+90=180. 5x=90 divide by five, x=18°
(3x2 + 9x + 6) − (8x2 + 3x − 10) + (2x + 4)(3x − 7)
First distribute the (2x+4)(3x-7) to get 6x2-2x-28
After this just add the like terms for all parts of the expression.
(3x2-8x2+6x2)+(9x-3x-2x)+(6+10-28)
x2+4x-12
So you answer is x2+4x-12
X=6 and y=-9. Not sure if y is correct since I kind of rushed but I hope this helps!
