Pleaseeee answer quick WILLL GIVE BRAINLIEST!!!!!! Given the expression: 5x10 − 80x2 Part A: Rewrite the expression by factoring

sladkih [1.3K]

Answer:

$5\,x^{10}-80\,x^2=5\,x^2\,(x^4+4)(x^2-2)(x^2+2)$

Step-by-step explanation:

First, extract the greatest common factor of the numerical as well as the variable parts:

the GCF of 5 and 80 is "5", and the GCF between $x^{10}$ and $x^2$ is $x^2$ , then:

$5\,x^{10}-80\,x^2=5\,x^2\,(x^8-16)$

Now, we can re-write the binomial in parenthesis as a difference o squares to be able to factor out even further:

$x^8-16=(x^4)^2-4^2=(x^4-4)(x^4+4)$

we now repeat the process for the binomial difference:

$(x^4-4)=((x^2)^2-2^2)=(x^2-2)(x^2+2)$

So finally the complete factorization is:

$5\,x^{10}-80\,x^2=5\,x^2\,(x^4+4)(x^2-2)(x^2+2)$

What is the total cost of $703 tablet computer that is on sale at 16% off if the local sales tax rate is 3%?

suter [353]

Answer: $608.24

Step-by-step explanation:

Hi, first we have to calculate the percentage amount of the discount.

We have to multiply the cost by the sale percentage in decimal form.

703 x (16/100) =703 x 0.16 =112.48

Then, we have to subtract that amount to the original cost.

703-112.48 = 590.52

Then, we have to calculate the sale tax amount by multiplying the sale cost by the tax percentage in decimal form.

590.52 x (3/100) = 590.52 x 0.03 =17.7156

Finally adding that amount to the sale cost.

590.52 +17.7156 = $608.24

11x+4<15

11x<11

x<1

From the second inequality,we got:

12x>-18

x>-3/2

Combine it together we got
