Answer:
2x^2 + 3x – 54 = (2x - 9) (x + 6), so A and F
Step-by-step explanation:
First way. you could round to the tens place and add. 370 + 230 about 600.
round to the nearest hundreds. 400 plus 200. about 600.
The same constant value(s)
Answer:
280 cm2
Step-by-step explanation:
1)find the area of square
A=LW
=10×10
=100
2) find the area of triangle
A=B×H÷2
=10×9/2
=45
Coz,there are 4 triangle we multiple by 4
=45×4
=180
3)find the total surface area by adding the two
=100+180
=280cm2
Answer: y=-2x + 3
Step-by-step explanation:
(0,3) and (2,-1)
3-(-1)= 4
0-2= -2
4/-2= -2 so the slope is -2 and we already know the y intercept is 3 because that is when x is 0.
so the equation will y= -2x + 3
