Mathematics
1 answer:
olga nikolaevna [1]3 years ago
3 0

Answer:

Commutative

Step-by-step explanation:

Given

3 + b + 2 = 3 + 2 + b

Required

What law is applied

The applied law is commutative law of addition.

This law states that:

a + b = b + a

So:

3 + b + 2 = 3 + (b + 2)

When the positions of 2 and b are interchanged, we have:

3 + b + 2 = 3 + (2 + b)

Remove bracket

3 + b + 2 = 3 + 2 + b

Explain why it is necessary to rename 4 1/4 if you subtract 3/4 from it? Help please.
Hitman42 [59]
<span>So we want to know why is it necessary to rename 4 1/4 if we subtract 3/4 from it. First, lets turn 4 1/4 into a fraction: 4 1/4 = 17/4. Now lets subtract 3/4 from it: 17/4 - 3/4 = 14/4. So 14/4 becomes 3 2/4. And now we see why is it necessary to rename 4 1/4. </span>

30 POINTS! Quilt squares are cut on the diagonal to form triangular quilt pieces. The hypotenuse of the resulting triangles is 3
Vesna [10]
C^2= a^2 + b^2                  a=b
34^2= a^2 + a^2
1156=2a^2
a^2=1156/2
a^2=578
a=24.04

The side length is 24.04
            Or I got this also
Using the special triangle theorem , an isosceles triangle has a diagonal equal to the square root of 2 of the legs of the triangle. In this case, the length of the legs is 34/ sqrt of 2 or equal to 24.04 units . This rule is based on the Pythagorean theorem
If the length of each side = x.

By Pythagoras' Theorem:

x² + x² = 34²

2x² = 34²

x² = 34² / 2

x² = 578

x = √578

<span>x ≈ 24.04 inches
hope this helps

What is the probability that the sun will rise tommorow?​
zvonat [6]

Answer:

100 percent the sun will rise tomorrow but who is to say you will get to see the sun tomorrow? who is to say you won't have a heart attack and die on this material planet tomorrow and won't get to see the sun rise. or what if the sun sends out a solar flare and burns everyone to a crisp and completely demolishes our ozone layer allowing oxygen to excrete from the planet and cooking everyone with solar radiation all at the same time catastrophic winds and earthquakes demolish the planet because of loss of pressure from the gravity field held in check by the oxygen that has left the planet from a destroyed ozone layer leaving everyone to suffocate and die and excruciating death therefore yes the sun will rise tomorrow but certain events are to unfold we could never prognosticate

What is the completely factored form of t4 − 16?
Mashcka [7]

we know that

A difference of squares problem can be factored as follows:

a^{2}-b^{2} =(a+b)(a-b)

in this problem we have

t^{4}-16

Applying difference of squares

t^{4}-16=(t^{2}-4)( t^{2}+4)

the term

(t^{2}-4)=(t+2)(t-2)

substitute

(t^{2}-4)( t^{2}+4)=(t+2)(t-2)( t^{2}+4)

therefore

<u>the answer is</u>

(t+2)(t-2)( t^{2}+4)
