Answer:
(3)11
Step-by-step explanation:
We are given that
We have to find the sum of positive roots of the equation.
Factor of 336
2,3,4,6,8,7,
Let x=2
x=2 is not the root of equation
x=-2
Hence x=-2 is the root of equation.
x+2 is a factor of equation.
x=3
Therefore, x=3 is the root of equation.
Positive roots are 3 and 8
Sum of positive roots=3+8=11
Option (3) is true.
Answer:
A) y= 5x - 3
Step-by-step explanation:
(5 • x) - 3 = y
Problem Solving:
5 • -6 = -30 - 3 = -33
5 • 3 = 15 - 3 = 12
5 • 9 = 45 - 3 = 42
5 • -4 = -20 - 3 = -23
5 • -5 = -25 - 3 = -28
Answer:
This is impossible, unless you meant centimeters. If you did, then the answer would be 113.
Step-by-step explanation:
225 - 112 = 113.
A quadratic equation is set up in the form of ax² + bx +c
First set equation = to 0
0= x² - 5x - 24
Next plug into quadratic formula( -b Plus or minus the √b²-4ac) ÷ 2a
[10 plus or minus √(25² - 4×1×24)] ÷ 2
Solve for inner parenthesis first
√625- 96 = √529
Now set up two equations
(10 + √529) ÷2 = x = 16.5
(10 - √529) ÷2 = x = -6.5
So therefore x = 16.5 and -6.5
It would be 115,000. You round down since 16 is closer to 115,000 than 116,000.
