Answer: x1 = -2, x2 = 3/4
Step-by-step explanation:
4x^2 + 5x -6 = 0
4x^2 + 8x -3x -6 = 0
4x(x+2)-3(x+2)=0
(x+2)(4x-3) = 0
x+2 = 0: x = -2
4x-3 = 0: x = 3/4
Answer:
See below.
Step-by-step explanation:
match the vocabulary word to its correct definition
1 additive identity
—the number 0 (for the numbers)
2 equation
—a mathematical sentence whose verb is ‘equal’ (=)
3 multiplicative identity
—the number 1 (for the real numbers
4 open sentence
—an equation that contains a variable or variables
5 symmetric property
—when the sides of an equation are interchanged, an equivalent equation is formed ; if a=b, then b=a

We cannot buy 1.68 gallons of paint and so the minimum we can buy is 2 gallons
Answer: 46 degrees
Step-by-step explanation: First you need to find the value of the vertical angle which is 180-(85+53) which is 42 degrees. Since vertical angles are congruent, you can say that 180-(42+92) is equal to x. When you solve it, you get x=46 which is your answer
