Answer:
a + b = 2
Step-by-step explanation:
Given
ax² + bx + c = 0 ( equation in standard form )
Then the sum of the roots = - 
3x² - 6x + 2 = 0 ← is in standard form
with a = 3, b = - 6 , then
sum of roots = -
= 2
Answer:
819
Step-by-step explanation:
to find the area of a shape you have to multiply lengths by width by height So Since this one is 7 ,13 and 9 multiply them together I think
Blaire has 20 tomato plants altogether.

<h3>What is a linear equation in two variables ?</h3>
An equation is linear if has highest degree of 1 and it has two variables.Generally they are in x and y.
For example -: 2x + 3y = 10
According to the given question a farmer has some hens and goats. He counts a total of 60 eyes and 86 feet between them.
Let us denote Hens by H and Goats by G.
We know both of them has 2 eyes each and we also know that a Hen has 2 legs and a Goat has 4 legs.
There fore the given data we can form two equations.
2H + 2G = 60 and 2H + 4G = 86.
Solving these two equations we have G = 13 and H = 17.
