-2x • 3x = -6x2 (the 2 is an exponent)
4y • -7y = -28y2 (the 2 is an exponent)
-2x • -7y = 14xy
4y • 3x = 12xy
14xy + 12xy = 26xy
—> -6x2(expo) - 28y2(expo) + 26xy
Check the answer again just to be sure, it’s been a while since I’ve had algebra!
Step-by-step explanation:
- 1a.2.
- b.1/2 base×height
- c.2 ×1/2 base×height
- base×height
b.
- 1m=100cm
- 1m²=100cm×100cm
- 1m²=10000cm²
- 0.25m²=0.25×10000cm²
- 0.25m²=2500cm²
C.
- .3
- .area of rectangle button+area of back+area of top
- d.total surface area =base×height+area of rectangle button+area of back+area of top
Answer:
The answer is z= 8/5, I attached a picture explaining! Lmk if u have any questions about it :)
Step-by-step explanation:
Answer: The answer is x^2+2xy+2y^2–3x–3y–1
Step-by-step explanation: Move 2 to the left of y^2.
X=11, set 10x+5x+15=180
15x+15=180, subtract 15 from 180= 165, then divide 165 by 15
