Answer:

h = 2

Step-by-step explanation:

I'm assuming your periods are multiplication signs.

(h + h) X (h X h) = 16

When adding two variables like the first set of parentheses, it would become 2h.  When multiplying two like variables, you add the exponents.  h is the same as writing h¹.  So h¹ x h¹   gives you the answer of h².

So now your equation would look like:

2h  X  h²  = 16

As above, when you multiply two like variables you would add the exponents.  Also if any number are in front of the variable you would multiply those numbers.  So you have 2h¹ x 1h² and that would be 2h³.  If it had been

2h¹ x 2h², your answer would have been 4h³.

But so far you have 2h¹ x 1h² = 16

2h³ = 16

Dividing both sides by 2 you get

h³ = 8

To find h you have to take the cubed root of 8.  What number multiplied by itself 3 times gives you 8?    2 x 2 x 2 = 8     2 x 2 = 4 and x 2 = 8.

h = 2

If you put this into the original equation you have:

(2 + 2) x ( 2 x 2) = 16

 ( 4 ) x ( 4 ) = 16

Answer:

=4x^2 +  3/2 x − 7

Step-by-step explanation:

Let's simplify step-by-step.

x /2  −3 + 4x^2 + x − 4  

=  1 /2 x + −3 + 4x^2 + x + −4

Combine Like Terms:

=  1 /2 x + −3 + 4x^2 +x + −4

= (4x^2) + (  1 /2 x + x) + ( −3+−4 )

= 4x^2 + 3 /2 x + −7

Answer:

30 pages per hour.

Step-by-step explanation:

Okay so they read 1 1/2 pages per hour right. And you need 20/20 to make 1 hour right. So all you have to do is multiply 1 1/2 by 20 and you got your answer.

Answer: 1 degree Fahrenheit

Step-by-step explanation:

The temperature starts at -10 degrees F, so if in two hours, the temperature has risen by 4 degrees, then the new temperature is -10 + 4 = -6 degrees F. 3 hours later, the temperature has risen another 7 degrees, so the new temperature is -6 + 7 = 1 degrees F. "addition equation" is ambiguous without knowing what class you are taking, but one such equation to represent the situation could be T = -10 + 4 + 7 = 1.

Answer:

Step-by-step explanation:

Given points:

Use slope formula:

[tex]\\ \sf\longmapsto Slope=m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\\ \sf\longmapsto m=\dfrac{-2+3}{-5+3}[/tex]

[tex]\\ \sf\longmapsto m=\dfrac{1}{-2}[/tex]

The value of x in the equation [tex]\frac{x}{2} = \frac{x^2}{x - 2}[/tex] are x = 0 and x = -2

The expression is given as:

[tex]\frac{x}{2} = \frac{x^2}{x - 2}[/tex]

Cross multiply

[tex]x(x - 2) =2 * x^2[/tex]

Open the bracket

[tex]x^2 - 2x =2x^2[/tex]

Collect like terms

[tex]- 2x =2x^2 - x^2[/tex]

Evaluate the like terms

[tex]- 2x =x^2[/tex]

Rewrite as:

[tex]x^2 + 2x =0[/tex]

Factor out x

x(x + 2)  =0

Expand

x = 0 or x + 2 = 0

Solve for x

x = 0 or x = -2

Hence, the value of x are x = 0 and x = -2

Speed of the current is 2 miles per hour

Step-by-step explanation:

The reason the current is 2 miles per hour is because it when going down stream they were going 14 miles per hour, going upstream they went 10. The difference is 4mph. So if the current pushes you 2mph when going down stream and holds you 2 mph when going up, the constant speed is 12mph then you add and subtract 2 becuase of the two directions youre traveling. hence 10mph and 14mph.

Answer:

Infinitely many

Step-by-step explanation:

They both equal the same equation

Answer:

All real numbers are solutions.

Step-by-step explanation:

4(z−5)+2=4z−18

Step 1: Simplify both sides of the equation.

4(z−5)+2=4z−18

(4)(z)+(4)(−5)+2=4z+−18(Distribute)

4z+−20+2=4z+−18

(4z)+(−20+2)=4z−18(Combine Like Terms)

4z+−18=4z−18

4z−18=4z−18

Step 2: Subtract 4z from both sides.

4z−18−4z=4z−18−4z

−18=−18

Step 3: Add 18 to both sides.

−18+18=−18+18

10.8 - -15.6 = 10.8 + 15.6 = 26.4

Answer:

Step-by-step explanation:

See the steps below:

First Method: (By splitting the middle term)

We have to find p and q such that p+q = 20 and

pq = 3×(-7) = -21

Let us looks for the pair of factors of -21 such that their sum is 20 and product is -21.

20 = 21 - 1 and -21 = 3(-7)

∴ 3x² + 20x - 7 = 3x² + 21x - 1x - 7

= 3x(x + 7) -1(x + 7)

= (x + 7)(3x - 1)

Second method: (Using the factor theorem)

Answer:

a. [tex]4^2[/tex]

b. 16

Step-by-step explanation:

The area of a square is equal to the side length squared. Normally, the area of a rectangle is length times width but since all sides are equal in a square it is just the side times the side. This can be simplified to side length squared.

Since the side length is 4 the exponent form of the area is simply 4 squared or [tex]4^2[/tex].

Then, compute this by multiplying 4*4. This equals 16 cms square.
