Your correct answer is: 2y^3+28y-12
 Let's simplify step-by-step. 6y3+17y−3−(4y3−11y+9)
Distribute the Negative Sign:
=6y3+17y−3+−1(4y3−11y+9)
=6y3+17y+−3+−1(4y3)+−1(−11y)+(−1)(9)
=6y3+17y+−3+−4y3+11y+−9
Combine Like Terms:
=6y3+17y+−3+−4y3+11y+−9
=(6y3+−4y3)+(17y+11y)+(−3+−9)
 =2y3+28y+−12
Answer: =2y3+28y−12

£880 is divided between Jim, Krutika & Natasha so that Jim gets twice as much as Krutika, and Krutika gets three times as mu
krok68 [10]

Answer:

264 pounds

Step-by-step explanation:

Write the question in the form of a ratio:

Natasha: Krutika: Jim

1:3:6

Now, we divide the amount of 880 in the ratio.

there are 10 parts in total.

1 part = 880 divided by 10 = 88.

since Krutika gets 3 parts, she gets 88 x 3 = 264

Find two different planes whose intersection is theline:x = 6 + 3ty = -8 - 3tz = -1 - tWrite equations for each plane in the for
alina1380 [7]

Answer:

x+y=-2 and 3z-y=5 are two such planes.

Step-by-step explanation:

To find the two planes whose intersection is the line

x=6+3t\\ y=-8-3t\\ z=-1-t

You can say that <em>t</em> is equal to this expression

t=\frac{x-6}{3} =\frac{y+8}{-3}=-z-1

Next,

\frac{x-6}{3} =\frac{y+8}{-3}\\ \frac{y+8}{-3}=-z-1

Then,

x+y=-2 and 3z-y=5 are two such planes.

You can see in the image attached that the intersection of this planes is the line

x=6+3t\\ y=-8-3t\\ z=-1-t

Anvisha [2.4K]

Answer:

x = 18 and x = 36

Step-by-step explanation:

let unknown value is x

6:x = 1:3

product of means = product of extremes

6*3 = 1 *x

18 = x

x:30=8:5

product of means = product of extremes

5x=180

x=180/5

x=36
