Elijah bought a rectangular for mat that was 1/2 meter long by 3/10 meter wide.How many square s is the door mat divided into

1 answer:

5 0

We can find the area of the doormat, in square meters, by multiplying 1/2 and 3/10, getting 3/20. Each square is 1/10*1/10=1/100 square meters.

(3/20)/(1/100) will give the ratio of the size of the doormat to the size of the squares, and thus the amount of squares needed. This is equal to 15 squares, so the doormat will be divided into 15 squares.

Ax4 + bx2 + c=0 (a>0) (c>0)

Irina18 [472]

The quadratic equation has two solutions if b^2 - 4ac > 0

Given the equation ax^4 + bx^2 + c=0

Let P = x^2

Substitute into the formula to have:

a(x^2)^2 + bx^2 + c =0

The equation becomes aP^2 + bP + c = 0

For us to have a unique solution, the discriminant b^2 - 4ac must be greater than zero. Hence the quadratic equation has two solutions if b^2 - 4ac > 0

Question one pls<br> algebra 2<br> logarithms

nirvana33 [79]

Condense the logarithm on the right side:

$3\log_b(p)-\left(2\log_b(t)+\dfrac12\log_b(r)\right)$

$n\log_b(m)=\log_b(m^n) \implies \log_b(p^3)-\left(\log_b(t^2)+\log_b\left(r^{\frac12}\right)\right)$

$\log_b(m)+\log(n)=\log_b(mn) \implies \log_b(p^3)-\log_b\left(t^2r^{\frac12}\right)$

$\log_b(m)-\log(n)=\log_b\left(\dfrac mn\right) \implies \log_b\left(\dfrac{p^3}{t^2r^{\frac12}}\right)$

So,

$x=\dfrac{p^3}{t^2r^{\frac12}}$

and $r^{\frac12}=\sqrt{r}$ , which makes (4) the correct choice.

Which of the binomials below is a factor of this trinomial?<br> x^2+8x+16

vaieri [72.5K]

<h3>Answer: x+4</h3>

This is because the given expression factors to (x+4)(x+4), which condenses to (x+4)^2.

To factor, think of two numbers that A) multiply to 16, and B) add to 8. Those values would be 4 and 4

4+4 = 8

4*4 = 16

So that's how we end up with (x+4)(x+4). You can use the FOIL rule to expand that out and get x^2+8x+16 again to help verify you have the correct factorization.
