Simply plug two in for x :)
f(2) = 4(2) × 2 + 5
f(2)=8 × 2 + 5
f(2)=16 + 5
f(2)=21
There's your answer :) (I just assumed that 2 was being multiplied when you said 4x2)

If 2/3 of a certain number is subtracted from twice the number, the result is 20. Find the number.

sleet_krkn [62]

Let x be the number.

Set up an equation:

2x - 2/3x = 20

Simplify:

1 1/3x = 20

Divide both sides by 1 1/3

X = 15

The number is 15

Please help . 20 points for right answer

You would add up the percentages first, which would bring everything up to 35%. You would then take the original cost of the item, which is $30 and multiple it by the 35%.

The equation would look like...

30 x .35 =

This will give you $10.50, which isn't the final answer.

You would then subtract 10.50 from the $30 that was asked for at the beginning by the retailer.

Your final answer is $19.50. :) Which isn't a bad deal if I say so myself.

For a polygon with 10 sides, which equation below represents the sum of the interior angles in the polygon?

jekas [21]

The sum of the interior angles in the polygon whose side is 10 is $1440^{0}$

<h3>What is sum of interior angle of polygon ?</h3>

The sum of the interior angles in a regular polygon is given by the formula 180(n – 2), where n is the number of sides in the polygon.

As, The formula for calculating the sum of interior angles is ( n − 2 ) × $180^{0}$

S0, n=10

Then, sum of interior angle be = (n-2) x 180

= (10-2) x 180

= 8 x 180

$= 1440^{0}$

Thus, the sum of the interior angles in the polygon is $1440^{0}$
