You would multiply the 3 $w^{2}$ to every term giving you,

12 $w^{5}$ $x^{2}$ + 6 $w^{4}$ x + 15 $w^{3}$ $x^{2}$

(Note that when multiplying a squared root number, you add the the exponents together. Also a term/number without an exponent is understood to have a 1 as the exponent, it is just not written)

There is a line whose Y intercept is -5 and whose slope is 0. What is its equation in slope – intercept form?

Aleonysh [2.5K]

<h2>Key Concepts</h2>

Linear equations
Slope-intercept form

Slope-intercept form looks like this: $y=mx+b$

<em>m</em> = slope
<em>b</em> = y-intercept

<h2>Solving the Question</h2>

We're given:

<em>m</em> = 0
<em>b</em> = -5

Plug the given values into y=mx+b:

$y=0x-5\\y=-5$

<h2>Answer</h2>

$y=-5$

20 is 40% of what number

tensa zangetsu [6.8K]

Is means equal

of means multiplication

so

20 = 40% x a

40% = 40/100 = 4/10 = 2/5

So

20 = 2/5 x a

Multiply both sides by 5/2

20 x 5/2 = a

10 x 5 = a

a =50

So your final answer is $\boxed{\bf{50}}$
