Answer:
Step-by-step explanation:
leading coefficient of 1 ==> a=1
sum of roots= 7+(-5)=2 ==> b= - 2
Product of roots=-35 ==> c=-35
Formula is<u> y=x²-2x-35</u>=(x-7)(x+5)
There would be 84 winning rows of 6 in a row.
On each face of a cube, there would be 6 vertical rows, 6 horizontal rows and 2 diagonal rows. That is a total of 14 rows per face.
A cube has 6 faces.
6 x 14 = 84
Answer:
x = 19
Step-by-step explanation:
These are vertical angles, which means that the angle measurements are going to be the same. Set the two angle measurements equal to each other:
3x - 3 = 6(x - 10)
Simplify. First, distribute 6 to all terms within the parenthesis:
3x - 3 = 6(x - 10)
3x - 3 = 6(x) - 6(10)
3x - 3 = 6x - 60
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 3 and subtract 6x from both sides:
3x (-6x) - 3 (+3) = 6x (-6x) - 60 (+3)
3x - 6x = -60 + 3
-3x = -57
Isolate the variable, x. Divide -3 from both sides:
(-3x)/-3 = (-57)/-3
x = -57/-3 = 57/3 = 19
x = 19 is your answer.

Step-by-step explanation:
Note the system of equation, PEMDAS. First, you solve parenthesis, then multiplication, then subtraction.
In this case, solve each of the expression given to us. Remember that parenthesis is first:
(12 - 23) * 2 = (-11) * 2 = - 22
12 - (3 * 2) = 12 - (6) = 6
- 22 ≠ 6

Answer:
7/10
Step-by-step explanation:
To find how many of x are y, you solve <em>y/x</em>.
With our numbers, we have <em>7/6 ÷ 5/3</em>.
We can turn that into <em>7/6 × 3/5</em> = <em>21/30</em> = 7/10.
