Answer:

Step-by-step explanation:

(3x^2-4x+10)(x^3+5x-20) =3x^5-4x^4+25x^3-80x^2+130x-200

x=1 is not a good value since when you plug it in you get -126 and you can't have a negative number of seeds.

Victor has saved $89.25 for the bicycle that he wants. The bicycle costs $129.85. Victor
serious [3.7K]

Answer:

Victor's equation did not correctly model the problem.

The equation that correctly modeled the problem:

$129.85-$89.25=$40.60

Step-by-step explanation:

The amount required for bicycle purchase by Victor is $129.85 out of which $89.25 has been saved,in other words,the balance required for Victor to reach his target purchase price is the difference between the total cost of $129.85 and the $89.25 already saved.

The balance required=$129.85-$89.25=$40.6

This shows that the equation put forward by Victor is wrong.

An equation that correctly represents the problem is the difference between the target savings and the amount already saved as stated above

Find the area of the composite shape
Alexxandr [17]

Answer:

13.735 ft^{2}

Step-by-step explanation:

Area of a circle.

A=\pi r^{2}

r=d/2\\r=8/2\\r=4

A=\pi \times 4^{2}

A=16\pi

A \approx 50.2654824574

Area of a square.

A=s^{2}

A=8^{2}

A=64

Subtract the area of the square with the area of the circle.

64-50.2654824574

= 13.7345175426

I hope it helps.

Brainliest much appreciated.
