factorise 3-x^2 can’t do it

Answers

Answer 1

Answer:

(√3 - x)(√3 + x)

Step-by-step explanation:

Use difference of two square formula:

a² - b² = (a - b)(a + b)

So a² = 3  ⇒  a = √3

and  b² = x²  ⇒  b = x

Therefore, 3 - x² = (√3 - x)(√3 + x)

For the right triangles below, find the values of the side lengths d and b.
Write answers in simplified radical form if necessary.

Answers

Answer:

d = 2√2b = 5√3

Step-by-step explanation:

In these special right triangles, the sides have length ratios ...

  45-45-90: 1 : 1 : √2

  30-60-90: 1 : √3 : 2

This tells us ...

  d×√2 = 4 . . . . . . . . . . relationship between the side and the hypotenuse

If Juan weighs 185 pounds, Luis weighs 95 kg and Pedro weighs 75 kg, how much do they all weigh together in pounds?

Answers

Answer:

744

Step-by-step explanation:

185 lbs

95 kg= 209.44 lbs (round to 209)

75 kg= 165, 35 lbs(roudn to 165)

185+209+165 = 744

185+209+165= 559

together they all weigh 559 pounds

[tex]\frac{24+95+76+60+15+48+80+75}{8}[/tex]

Median = Put all numbers in order from least to most and use the middle one, if there are two, use the mean of those two

Hope makes 3 group of shapes
What Larger group to the shapes in a and B belong in

Answers

The shapes in the three groups are quadrilaterals

The shapes in group A and B belong to parallelograms and rectangles

How to determine the shapes?

From the complete question, we can see that the shapes in the group A have opposite parallel sides and the angle between the adjacent sides is not 90 degrees.,

This means that the shapes in group A are parallelograms

Similarly, the shapes in the group B have opposite parallel sides and the angle between the adjacent sides is 90 degrees.

This means that the shapes in group A are rectangles

Hence, the shapes in group A and B belong to parallelograms and rectangles

Write an equation in slope-intercept form for the line that passes through the given point and has the given slope:

Slope = -1

PLS HELP PLS PLS TYSM

Answers

Answer:

y = -x + 6

Step-by-step explanation:

We can plug the given point and slope into the point-slope formula and solve for the y-intercept formula.

y - y = m(x - x)  <-- Point-Slope Formula

m = -1

(x,y) = (1, 5)

The radius of a sphere is 3 cm. What is the sphere's volume? Round to the nearest tenth.

Answers

Answer:

I answered this question before with the exact radius, and I remember the answer being this.

Formula:

V=4

3πr3=4

3·π·33≈113.09

Hope this helps!

Answer:

Step-by-step explanation:

the answer is 113.1 cm³

The volume of a sphere of radius r is V = (4/3)πr³.

If the radius is 3 cm and the answer is to be expressed to the nearest tenth, then we get:

V = (4/3)(3.14159)(3 cm)³

  = (4/3)(84.82 cm³

   = 113.1 cm³

Problem 3

Answer: Choice A and Choice C

-----------------------

Explanation:

Think of stacks of coins. Let's say we had 2 stacks of 10 quarters each. The quarters are identical, so they must produce identical volumes. Those sub-volumes then add up to the same volume for each stack. Now imagine one stack is perfectly aligned and the other stack is a bit crooked. Has the volume changed for the crooked stack? No, it hasn't. We're still dealing with the same amount of coins and they yield the same volume.

For more information, check out Cavalieri's Principle.

With all that in mind, this leads us to choice C. If the bases are the same, and so are the heights, then we must be dealing with the same volumes.

On the other hand, if one base is wider (while the heights are still equal) then the wider based block is going to have more volume. This leads us to choice A.
