Just substitute their values into the expression:
= -8 + 9 + 5z + 7x
= -8 + 9 + 5(3) + 7(5)
= 1 + 15 + 35
= 51

In short, Your Answer would be 51

Hope this helps!

If n is a positive even number, then the product of (-12)ⁿ will be what
kipiarov [429]

Answer:

a positive even number.

Step-by-step explanation:

I suggest plugging in random positive even numbers and finding a pattern. (-12)^2 = 144. (-12)^ 4= 20,736. this is because two negatives, when multiplied, turn to a positive. the n is how many times negative 12 is multiplied with itself

Add 212+(−13) . Write your answer as a mixed number in simplest form.
nordsb [41]

The value of the given expression after addition is 199 and this can not written as a mixed number in the simplest form.

According to the question,

We have the following expression:

212+(-13)

Now, we know that the multiplication of one negative and one positive integers is always positive.

So, we have the following expression:

212-13

199

Now, this number is whole number and it can not be written as a mixed number. It could only have been written as a mixed number when the result would have been in a fraction.

Hence, the value of the given expression after addition is 199 and this can not written as a mixed number in the simplest form.

What is the value of x?
Talja [164]
Use the Pythagorean theorem. The Pythagorean Theorem uses the following formula:

a^{2} + b^{2} = c^{2}

Plug in the known values into the equation:

a = 6, c = 10

6^{2} + b^{2} = 10^{2}

36 + b^{2} = 100

Subtract both sides by 36.

b^{2} = 64

Square root both sides to get b by itself.

\sqrt{64} = 8

b = 8

The value of x is 8.

How many solutions does the equation have?
Salsk061 [2.6K]

Answer: there is only one solution

Step-by-step explanation:

Combine like terms by performing the opposite operation of subtracting 4x on both sides of the equation

The 4x's will cross out on the right

4x - 4x = 0x = 0

On the left:

2x - 4x = -2x

Now the equation looks like:

-2x + 3 = 2

Continue to combine like terms by subtracting 3 on both sides of the equation

On the left:

3 - 3 = 0

On the right:

2 - 3 = -1

Equation:

-2x = -1

Isolate x by performing the opposite operation of dividing -2 on both sides of the equation

On the left:

-2x ÷ -2 = 1

On the right:

-1 ÷ -2 = 1/2

x= 1/2
