2) What are the possible zeros of the following equation?<br> y = 3x4 + 4x² – 5x + 10

Nana76 [90]

Answer:

Solution:

(4x2 - 2x) - (-5x2 - 8x)

= 4x2 - 2x + 5x2 + 8x.

= 4x2 + 5x2 - 2x + 8x.

= 9x2 + 6x.

= 3x(3x + 2).

Answer: 3x(3x + 2)

jonathan ran 5 days this week. the most he ran in one day was 3.5 miles. write an inequality that shows the distance jonathan co

poizon [28]

Let m represent the number of miles this guy runs in a day.
He runs every day, so the minimum number of miles has to be greater than 0.
According to the problem statement, the max number of miles is 3.5 miles or less.

Translate this into a (symbolic) inequality.

Maggie constructs a triangle with sides lengths 7 centimeters long and 10 centimeters long.

MakcuM [25]

7 centimeters is a possible length for the third side ⇒ B

Step-by-step explanation:

Let us revise the triangle Inequality Theorem

The sum of the lengths of any 2 sides of a triangle must be greater than the length of the third side
To prove that by easy way add the smallest two sides, if their sum greater than the third side,then the sides can form a triangle

Assume that the length of the third side is x cm

∵ The length of two sides are 7 cm and 10 cm

∵ The length of the third side is x cm

- Put the sum of x and 7 greater than 10 ( x and 7 are the smallest sides)

∴ x + 7 > 10

- Subtract 7 from both sides

∴ x > 3

- Put the sum of 7 and 10 greater than x (7 and 10 are the smallest sides)

∵ 7 + 10 > x

∴ 17 > x

∴ x < 17

- By using one inequality for x (combined the two inequalities in one)

∴ 3 < x < 17

That means the length of the third side is any number between 3 and 17

There is only one answer between 3 and 17

∵ 7 is between 3 and 17

∴ The length of the third side could be 7 cm

7 centimeters is a possible length for the third side
