There is no such real number!

a+b=-5

ab=625

a=-b-5

(-b-5)*b=625

-b^2-5b=625

b^2+5b+625=0

b=-5+-sqrt(25-2500)

This resulting in b as a complex number which means in the real numbers there is no such solutions!

<h3>Answer:</h3><h2><em><u>There are no numbers</u></em></h2>

Step-by-step explanation:

H+I=-5

HI=625

H=-b-5

I is a compounded number, so in other words there are no solutions for it.

Answer I got:

I got approximately 0.34906585039 in².

Step-by-step explanation:

So we know that $A=\pi r^{2}$ . We also know that $r=\frac{1}{3}(0.3333...)$ in. So, we can place this into our equation:

$A=\pi\times\frac{1}{3}^{2}(A=\pi\times0.33333...^{2})$

Finally, we know that $\pi\approx\frac{22}{7}$ .

$A\approx\frac{22}{7}\times\frac{1}{3}^{2} (A=3.1415926...\times 0.3333333...^{2})$

This gave my final approx. answer of 0.34906585039 in².

$\pi\frac{1}{3}^{2}\approx 0.34906585039$

All you need to do now is find the corresponding fraction to that!

(2c-6) (5c²+5) what would this be for multiplying polynomials

solniwko [45]

Answer:

10c^3 -30c^2 + 10c -30

Step-by-step explanation:

2c(5c^2+5) - 6(5c^2+5)

= 10c^3 + 10c - 30c^2 - 30

= 10c^3 -30c^2 + 10c -30
