Choose the product of -3y2–4y + y -9). A. -7y5 – 3y - 27y2
B. 12y – 3y2 + 27y2
C. 12y - 3y2 + 12y2
D. 12y5 – 3y2 + 27y

54

step-by-step explanation:

6x9

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base

option a

answer: given the scale 3,5 mm to 1 foot: so you know this and you need convert this 150mm to get the right answer.
