The equivalent expression is 30x + 15y
<em><u>Solution:</u></em>
Given that we have to find the equivalent expression for given expression
<em><u>Given expression is:</u></em>
5(6x + 3y)
We can find the equivalent expression by using distributive property
The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.
<em><u>By distributive property,</u></em>
a(b + c) = ab + ac
Therefore, in given expression 5(6x + 3y), 5 can be multiplied with both 6x and 3y
![\rightarrow 5(6x + 3y) = 5 \times 6x + 5 \times 3y](https://tex.z-dn.net/?f=%5Crightarrow%205%286x%20%2B%203y%29%20%3D%205%20%5Ctimes%206x%20%2B%205%20%5Ctimes%203y)
Multiply the numbers and simplify
![\rightarrow 5(6x + 3y) = 5 \times 6x + 5 \times 3y = 30x + 15y](https://tex.z-dn.net/?f=%5Crightarrow%205%286x%20%2B%203y%29%20%3D%205%20%5Ctimes%206x%20%2B%205%20%5Ctimes%203y%20%3D%2030x%20%2B%2015y)
Thus the equivalent expression is 30x + 15y
0.750,and 0.955 because both have 5s in the hundredths place
Answer:
If Discriminant,![b^{2} -4ac >0](https://tex.z-dn.net/?f=b%5E%7B2%7D%20-4ac%20%3E0)
Then it has Two Real Solutions.
Step-by-step explanation:
To Find:
If discriminant (b^2 -4ac>0) how many real solutions
Solution:
Consider a Quadratic Equation in General Form as
![ax^{2} +bx+c=0](https://tex.z-dn.net/?f=ax%5E%7B2%7D%20%2Bbx%2Bc%3D0)
then,
is called as Discriminant.
So,
If Discriminant,![b^{2} -4ac >0](https://tex.z-dn.net/?f=b%5E%7B2%7D%20-4ac%20%3E0)
Then it has Two Real Solutions.
If Discriminant,![b^{2} -4ac < 0](https://tex.z-dn.net/?f=b%5E%7B2%7D%20-4ac%20%3C%200)
Then it has Two Imaginary Solutions.
If Discriminant,![b^{2} -4ac=0](https://tex.z-dn.net/?f=b%5E%7B2%7D%20-4ac%3D0)
Then it has Two Equal and Real Solutions.
