True and false. To solve the equation 5x=-20 you can use the multiplication property of Equality. Explain your reasoning

Answer: False

Step-by-step explanation: In this equation, the Multiplication Property of Equality wouldn't help us because it tells us we can always multiply the same quantity times both sides of an equation.

Since we want to be able to get x by itself, multiplying both sides

of the equation by the same quantity wouldn't help us.

Instead, we would use the Division Property of Equality.

In order to get from the statement 5x = -20  to the statement where x

is isolated, we must divide both sides of the statement, 5x = -20, by 5.

So we have x = -4.

So this statement uses the Division Property of Equality.

Answer:

true, both sides are divisible by 5

Step-by-step explanation:

5x=-20

÷5 ÷5

x= -4

To evaluate the expression all you have to do is substitute the value for the variable.

3 + y + 6, y = 5
3 + 5 + 6
8 + 6
14.

The solution is 14.

First, we are going to find the vertex of our quadratic. Remember that to find the vertex (h,k) of a quadratic equation of the form y=a x^{2} +bx+c, we use the vertex formula h= \frac{-b}{2a}, and then, we evaluate our equation at h to find k.

We now from our quadratic that a=2 and b=-32, so lets use our formula:
h= \frac{-b}{2a}
h= \frac{-(-32)}{2(2)}
h= \frac{32}{4}
h=8
Now we can evaluate our quadratic at 8 to find k:
k=2(8)^2-32(8)+56
k=2(64)-256+56
k=128-200
k=-72
So the vertex of our function is (8,-72)

Next, we are going to use the vertex to rewrite our quadratic equation:
y=a(x-h)^2+k
y=2(x-8)^2+(-72)
y=2(x-8)^2-72
The x-coordinate of the minimum will be the x-coordinate of the vertex; in other words: 8.

We can conclude that:
The rewritten equation is y=2(x-8)^2-72
The x-coordinate of the minimum is 8

Two brothers want to share a large field equally.
Elan Coil [88]

Yes, the partition gives the two brothers equal shares.

Step-by-step explanation:

Step 1:

Assume the entire field has an area of B. So one brother takes \frac{1}{12} B, \frac{1}{6}B, and \frac{1}{4} B

So we need to calculate how much this brother takes in terms of B.

To do this we calculate how much \frac{1}{12} B + \frac{1}{6} B + \frac{1}{4} B is.

Step 2:

To add \frac{1}{12} B + \frac{1}{6} B + \frac{1}{4} B,

First take the LCM of the denominators 12, 6, and 4

The LCM is 12, we multiply the denominator to get the LCM value, this same value is multiplied to the numerator too.

\frac{1}{12} B + \frac{1}{6} B + \frac{1}{4} B = \frac{1(1)}{12(1)} B + \frac{1(2)}{6(2)} B + \frac{1(3)}{4(3)} B \\\\\frac{1}{12} B + \frac{1}{6} B + \frac{1}{4} B= \frac{1B +2B+3B}{12} = \frac{B}{2}

Step 3:

One brother gets \frac{1}{2} B, so we need to calculate how much the other brother gets.

The other brother's share = B - \frac{1}{2} B = \frac{1}{2}B

So both the brothers get equal shares
