Answer: B
Begin by simplifying the given equation, so it's rearranged into standard form. Move all the terms onto one side, so they equal 0. This would result with -3x-9=0. Quadratic formula is (-b±√(b²-4ac))/(2a). Standard form follow this variable format:
+bx+c. Use the numbers that correspond with each variable to substitute them into the quadratic formula. This would be
(-(-3)±√(-3²-4(4)(-9)/2(4).
Answer:
31.5 m^2
Step-by-step explanation:
To find the amount for 7 bags, create a proportion.
To solve for y, cross multiply numerator to denominator of each fraction.
4(y) = 18(7)
4y= 126
y= 31.5
7 bags will do 31.5 m^2
Answer:
Part 1) The numbers are 22,24 and 26
Part 2) The value of x has no solution
Part 3) The value of x has no solution
Part 4) The value of x is
Step-by-step explanation:
Part 1)
Let
x ----> the first even number
x+2 ---> the second consecutive even number
x+4 ---> the third consecutive even number
we know that
Solve for x
therefore
The numbers are 22,24 and 26
Part 2) we have

therefore
The value of x has no solution
Part 3) we have
Distribute in the left and the right side to remove the parenthesis
Combine like terms
-----> is not true
therefore
The value of x has no solution
Part 3) we have
Distribute in the right side to remove the parenthesis
