Answer:

Company A is 1.99 times B.

Step-by-step explanation:

Company A charges:

A=70.50+0.50=\$71/mile  

Company B charges:

B=35.50+0.09=\$35.59/mile

We just need to divide A by B:

x=A/B=1.99

Therefore, company A is 1.99 times B.

I hope it helps you!

Answer:

The correct statements are:

A) This polynomial has a degree of 2, so the equation x^{2}  + 4x + 4has exactly two roots.

B: The quadratic equation x^{2}  + 4x + 4 has one real solution, x=−2, and therefore has one real root with a multiplicity of 2.

Step-by-step explanation:

Here, the given polynomial is  f(x) = x^{2}  + 4x + 4

FUNDAMENTAL THEOREM OF ALGEBRA:

If P(x) is a polynomial of degree n ≥ 1, then P(x) = 0 has exactly n roots, including multiple and complex roots.

Now, here the given polynomial is a quadratic polynomial with degree 2.

So, by the fundamental theorem, f(x) has EXACTLY 2 roots including multiple and complex roots.

Now, solving the equation , we get that the only possible roots of the polynomial p(x) is x = -2 and x = -2

So, f(x) has only one distinct root x = -2 with a multiplicity 2.

Hence, the correct statements are:

A) This polynomial has a degree of 2, so the equation x^{2}  + 4x + 4has exactly two roots.

B: The quadratic equation x^{2}  + 4x + 4 has one real solution, x=−2, and therefore has one real root with a multiplicity of 2.

Maya needs $58 to go on a field trip. She has saved $18.50. She earns $6.50 per hour cleaning her neighbor's garden, and she ear
insens350 [35]

She has $18.50 so she needs $39.50.

6.50×3= 19.50

18.50+19.50= 38

5.25×4=21

38+21=59

Maya would have enough money to go on the trip.
