Combine like terms to create an equivalent expression. 7.4z−5(−1.6z+2.4)
ryzh [129]

Answer:   15.4z-12

Step-by-step explanation:

For this exercise it is important to remember:

  • The Distributive property:

       a(b\±c)=ab\±ac

  • The multiplication of signs:

        (+)(+)=+\\\\(-)(-)=+\\\\(-)(+)=-

Then, given the following expression:

7.4z−5(-1.6z+2.4)

You need to  apply the Distributive property. Then:

=7.4z+8z-12

Now you can combine like terms (or add the like terms). Then you get:

=15.4z-12

Therefore, the equivalent expression created by combining like terms, is:

 15.4z-12

The radius of the circle x^2+y^2 +px+6y-3=0 is 4. find the possible values of p​
worty [1.4K]

Here, the given equation is,

x^2+y^2+px+6y-3=0

By copairing it with x^2+y^2+2gx+2fy+c=0, we get,

2g=p or, g=p/2

2f=6 or, f=3

c=-3

now the radius is,

r^2=g^2+f^2-c

or, 4^2=(p/2)^2 +3^2 -(-3)

or, 16= p^2/4 +9+3

or, 16-9-3=p^2/4

or p^2/4=4

or, p^2=4×4

or p^2=4^2

or p=4

therefore the rewuired value of p is 4.

Math 7a using number sense to solve equations
Anika [276]
Simple...

you have: \frac{n}{3} =12


and

\frac{n}{3} =-12

To solve for....\frac{n}{3} =12

Multiply to remove the denominator-->>

3*  \frac{n}{3} =12*3

n=12*3

n=36

Then-->>>

\frac{n}{3} =-12

Do the same thing-->>

3* \frac{n}{3} =-12*3

n=-12*3

n=-36

Thus, your answer.
