Answer:

Step-by-step explanation

Cost of 2.5 kg potatoes = £ 1.40

Cost of 1 kg potato = 1.40/2.5

Cost of 4.25 kg of potatoes = (1.40/2.5}*4.25

$=\frac{1.40*4.25*10}{2.5*10}\\\\=\frac{14*4.25}{25}\\\\$

= £2.38

Expand . ( 3x –2 ) 2 please help me with this.

Answer: $\textsf{9x}^2\textsf{ - 12x + 4}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{(3x - 2)}^2$

Find: $\textsf{Simplify the expression}$

Solution: It looks like 2 is at the end of the parenthesis where the power would be instead of distributing the number. If so the following steps would be followed.

Expand

$\textsf{(3x - 2)}^2$

$\textsf{(3x - 2)(3x - 2)}$

$\textsf{(3x * 3x) + (3x * (-2)) + (3x * (-2)) + (-2 * (-2))}$

Simplify

$\textsf{9x}^2\textsf{ - 6x - 6x + 4}$

$\textsf{9x}^2\textsf{ - 12x + 4}$

Therefore, after following the provided information we are able to determine that the expanded form would be 9x^2 - 12x + 4.

A man traveled 24 miles in 20 minutes and 18 miles in 15 minutes. Assume that the distance varies linearly with time. How far wi

Norma-Jean [14]

Step-by-step explanation:

First we need to get his speed:

speed = distance / time

If he travelled 24 miles in 20 mintues, his speed is 24 / 20 = 1.2 miles per minute

If he travelled 18 miles in 15 minutes, his speed is 18 / 15 = 1.2 miles per minute

Those two should give us the same answer since it says that the distance varies linear with time, which means that his speed is constant.

Then after 30 minutes he will have traveled: 1.2 x 30 = 36 miles
