Identify all factors of the expression 〖4x〗^2+17x-15.

Mathematics

Basile [38]3 years ago

The factors of given expression are: -5 and 3/4

Step-by-step explanation:

Given equation is:

4x^2+17x-15

Making pairs for the mid-term 17x by factoring the product of co-efficient of 4x^2 and 15

4x^2+20x-3x-15

= 4x(x+5) - 3(x+5)

=(4x-3)(x+5)

Now

4x-3 = 0\\4x = 3\\x = \frac{3}{4}

x+5 = 0\\x = -5

Hence,

The factors of given expression are: -5 and 3/4

Which equation would you use to find how high the bird is flying?
damaskus [11]

Answer:

The first one

Step-by-step explanation:

An easy way is SOH CAH TOA

SOH is that you use sine if you there is the opposite (in this case the question mark) and hypotenuse (the diagonal line)

CAH is that you use cosine for the adjacent side (1100) and the hypotenuse.

TOA is using tangent for the opposite and adjacent side.

To fine the question mark, you would use tangent. And plug in the given (1100 for the adjacent). So tan45 = x/1100.

If you need more help or clarification, let me know!

The scouts packed 9 boxes of different kinds of chips for their trip. Each box had 10 bags of chips. These clues show what they
Katarina [22]

The scouts eat 51 bags of chips on their trip

<h3>How to determine the number of bags of chips?</h3>

The given parameters are:

Boxes = 9

Bag = 10 chips

2 full boxes of potato chips and 3 bags left over.

This represents:

Potato chips = 2 * 10 + 3

Potato chips = 23 i.e. 23 bags potato chips are left over

1 fewer box of nacho chips than potato chips, with no bags left over

This represents

Nacho chips = (2 - 1) * 10

Nacho chips = 10 i.e. 10 bags of nacho chips are left over

The loose bags of potato chips is 3.

So, we have:

Barbecue chips = 2 * 3 bags

Barbecue chips = 6 bags

At this point, we have:

  • Potato chips = 23 bags
  • Nacho chips = 10 bags
  • Barbecue chips = 6 bags

The total number of bags left over is

Total = 23 + 10 + 6

Total = 39

The number of bags eaten is:

Eaten = 9 * 10 - 39

Evaluate

Eaten = 51

Hence, the scouts eat 51 bags of chips on their trip

Hey! pls help me with this question on angles. would really be appreciated. have a nice day.
Neko [114]

Using supplementary angles, it is found that the measures of the angles are given as follows:

  • m<a = 30º.
  • m<b = 90º.

<h3>What are supplementary angles?</h3>

Supplementary angles are two angles whose sum is of 180º.

An interior angle is supplementary with it's exterior angle, hence:

m<a + 150º = 180º -> m<a = 30º.

The sum of the three interior angles of a triangle is of 180º, hence:

30º + m<b + 60º = 180º

90º + m<b = 180º

m<b = 90º.
