I think just GCF. That is the only one I think
Step-by-step explanation:
EQUATION: Volume=length x width x height.
V=l×w×h
1620cm^3=9cm×9cm×xcm
1620cm^3=81cm^2 ×xcm
xcm= 1620cm^3/81cm^2
xcm= 20cm
Answer:
3060
Step-by-step explanation:
<u>Find the cross-sectional area first of the trapezium</u>
So,
which is 40 / 2 x 15 = 20 x 15 = 300
Since there are 2 trapeziums (on the front and back): 300 x 2 = 600
<u>Find the Area of the Rectangles</u>
The first rectangle on the top would be: 6x30 = 180
The slanted rectangle on the right would be: 25x30 = 750
The rectangle on the bottom would be: 30x34 = 1020
The hidden rectangle on the left would be: 17 x 30 = 510
So by combining all these calculations, you will get the total surface area which is:
600 + 180 + 750 + 1020 + 510 = 780 + 1770 + 510 = 2550 + 510 = 3060

i hope this helps
Answer:
Vertex is (-4,3)
Step-by-step explanation:
rewrite the problem from y=-2(x+4)^2+3 to y=ax^2+bx+c
y=-2x^2-16x-29
the parabola points are: a=-2 b=-16 c=-29
then divide x= -b/2(a)
x= -(-16)/2(-2)
simplify: x=-4
go back and plug in x=-4 to get y
y=3
Answer is (-4,3)
