The legs of an isosceles triangle have lengths x+1 and -x+7 . The base has length 3x-3. What is the length of the base? a. 6
b. 3
c. 4
d. cannot be determined

Answers

Answer 1

Answer:
The only thing I'm a little unclear on here is what you mean by
the "legs" of an isosceles triangle.

I'm going to assume that your isosceles triangle is standing on
the side you call the "base", and the "legs" are the two slanty ones,
standing up, which are the two equal sides.

With that set-up,    x + 1 = -x + 7

Add x to each side:    2x + 1 = 7

Subtract 1 from each side: 2x      = 6

Divide each side by 2 : x   =    3

Finally, if the base is (3x - 3), then that's (3·3 - 3) = 6 .

Factor completely x3 + 2x2 – 15x

Answers

$x^3 + 2x^2 - 15x$

first we can factor out an x
$x(x^2 + 2x - 15)$

then we find a pair of numbers that multiply to -15 and add up to 2

this would be 5 and -3
because 5 times -3 = -15
and -3 + 5 = 2

we would then get
$x(x-3)(x+5)$

this would be you answer :)

Hi Lisa

x³ + 2x² - 15x

= x( x-3)(x+5)

Need help asap!Select the most precise and correct definition of parallel lines from among those that are given.

A.Two distinct lines are parallel if they are in the same plane and never intersect each other.

b.Two distinct lines are parallel if they point in the same direction.

c.Two distinct lines are parallel if one can be rotated to sit on top of the other.

Answers

Option (B) that is Two distinct lines are parallel if they are in the same plane and never intersect each other is correct.

What is a perpendicular line?

A Lines that intersect at a right angle are named perpendicular lines. Lines that are always the same distance apart from each other are known as parallel lines.

We know from the definition of the lines:

The line is a ray that goes infinitely from both sides.

In the perpendicular lines, they intersect at 90 degrees angles or right angles.

In the parallel lines, they never intersect and go parallel infinitely from both sides.

We have choices:

Choice A that is Two distinct lines are parallel if one can be rotated to sit on top of the other.

Choice B that is Two distinct lines are parallel if they are in the same plane and never intersect each other.

Choice C that is Two distinct lines are parallel if they point in the same direction.

The most precise and correct definition of parallel lines is two distinct lines are parallel if they are in the same plane and never intersect each other.

Thus, option (B) that is Two distinct lines are parallel if they are in the same plane and never intersect each other is correct.

Last year a large trucking company delivered 9.0 x 105 tons of goods with an average value of $17,000 per ton. What was the total value of the goods delivered? Write the answer in scientific notation

Answers

So, we have 9×105 tons of goods. Which gives us a total of 945 tons.

These goods have the average value of 17000 per ton. When we turn that into an equation we got: $945 * 17000 = 16065000$

When we convert that into scientific notation, we can write that as: $1.6065 * {10}^(7)$

A student runs 100 meters in 11 seconds. What is the speed of the student? 9.1 miles per hour 16miles per hour 20.3miles per hour 24miles per hour

Answers

The answer is 20.3 miles per hour. First, you need to change meter and second to mile and hour. The 100 meter equals 100/1609 mile. 11 seconds equals 11/3600 hour. Then using mile number divides by hour you can get the answer.
