Answer:
(3x + 5)(2x - 3) = 6x² + x - 15
Step-by-step explanation:
To find the product of two binomials, we could use the FOIL method.
First
Outer (Outside)
Inner (Inside)
Last
(3x + 5)(2x - 3) = (3x)(2x) + (3x)(-3) + (5)(2x) + (5)(-3) = 6x² - 9x + 10x - 15 = 6x² + x - 15
So the product of the two binomials would be 6x² + x - 15.
I hope you find my answer and explanation to be helpful. Happy studying.
Answer:
The ball will hit the ground in 1.33 s if no one touches it. The equation has 2 real solutions.
Step-by-step explanation:
The ball will hit the ground when its height is equal to 0 meters, therefore using this value in the expression and solving for "t" will give us the correct solutions.
The ball will hit the ground in 1.33 s if no one touches it. The equation has 2 real solutions.
Answer:
72
Step-by-step explanation:
The two digit number can be represented by xy, where x and y must add to 9 and x - y must subtract to 5. Make a system of equations.
Use the elimination method and add the terms from top to bottom like so. The y and -y cancel out.
2x = 14
Divide both sides by 2.
x = 7
Substitute 7 for x into the first equation (either eqn would work).
(7) + y = 9
Subtract 7 from both sides.
y = 2
Combine these two together; xy --> (7)(2) --> 72.
The number is 72.
