√x+7 The solution to the equation is x=-3.

Square root: If we take the square root of a number and then take the square of the outcome, we get the original number back again.

   e.g.  4 = 2 and 22 = 4.

We can say that the square root and the square cancel each other out. They are the inverse of each other.

If we have a number written with the index 2 ( squared) then taking the square root simply means that we leave out the 2 ( this only applies to positive numbers ).

We can therefore take any squared numbers that are under the square root sign out from under the root sign by leaving out the power 2.

The solution to the equation√x+7= -2.

√x+7= -2

First we take Squaring on both sides

(√x+7)2= (-2)2

x+7 = 4

x=-3.

∠1 and ∠ 2 are linear pairs and have a sum of 180° so they will be supplementary angles.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

In the given image ∠1 and ∠ 2 are linear pairs.

Now,

∠1 = ∠3 (opposite angle)

∠2 = ∠4 (opposite angle)

Now,

∠1 + ∠2 + ∠3 +∠4 = 360°

(∠1 + ∠2) + 180° = 360°

(∠1 + ∠2) = 180°

If the sum of two angles is 180° then they will be supplementary angles.

Hence "∠1 and ∠ 2 are linear pairs and have a sum of 180° so they will be supplementary angles".

Answer:

The triangle has sides lengths 28, 56, 48

Step-by-step explanation:

Let x = the shortest side

So then the longest side will be 2x, because the question said that "the longest side... is twice the length of the shortest side" Then the third side would be x + 20.

The perimeter was given so add all the sides and set it equal to 132.

x + 2x + x + 20 = 132

Combine like terms.

4x + 20 = 132

Subtract 20

4x = 112

Divide by 4.

x = 28

Then use x = 28 to find the lengths of all the sides.

Shortest Side:

x = 28

Longest Side:

2x

= 2(28)

= 56

Third Side:

x + 20

= 28 + 20

= 48

The GCF of [tex]12w^{2} - 4w^{3}[/tex] is [tex]4w^{2}[/tex].

The Greatest Common Factor (GCF) of two or more numbers is defined as the factors which is common and highest .

For Example The GCF of 6 and 8

express 6=2*3

             8=2*2*2.    since 2 is common in both the GCF is 2.

In the given question

we need to factor out gcf from [tex]12w^{2} - 4w^{3}[/tex]

first express both terms in prime factors

[tex]12w^{2} =3*4*w*w[/tex]

and

[tex]4w^{3} =4*w*w*w[/tex]

the equation becomes

[tex](3*4*w*w-4*w*w*w)[/tex]

we can see that [tex]4*w*w[/tex] is common in both the terms .

So we can write [tex]4w^{2} (3-w)[/tex]

When Angelo drove home from college with an average speed of 71.7 mph and back to college with an average speed of 64.1 mph, she took 5 hours for full trip then the time taken to travel from home to college is 2.63 hours

Given,

The average speed from college to home = 71.7 mph

The average speed from home to college = 64.1 mph

We know,

Speed =  Distance / Time

Consider the total distance as x

Time taken = Distance / Speed

Then the time taken to travel from college to home  = [tex]\frac{x}{71.7}[/tex] hours

time taken to travel from home to college = [tex]\frac{x}{64.1}[/tex] hours

Total time taken = 5 hours

Then the equation will become

[tex]\frac{x}{71.7}+\frac{x}{64.1}=5[/tex]

Cross multiply the terms

[tex]\frac{64.1x+71.7x}{(71.7)(64.1)}=5\\ \frac{135.8x}{4595.97}=5[/tex]

135.8x= 5×4595.97

135.8x=22979.85

x=169.21

Time taken to travel from home to college =[tex]\frac{169.21}{64.1}[/tex]
