X^2+3x
(3/2)^2=9/4 must be added to complete the square
Answer:
10 cars
Step-by-step explanation:
37 ÷ 4 = 9.25
Because this is dealing with people, not numbers, there can't be a remaining 0.25 person. There's one extra person that doesn't cleanly fit into the 9 other cars, so a tenth car is needed for that person.
Answer:
25
Step-by-step explanation:
I'll explain in detail for those of you that want to know.
You know that since angles B and C are congruent to each other that this triangle is an isosceles triangle. Therefore, sides AB and AC are congruent to each other because that is a property of an isosceles triangle.
To solve for x, place the expressions of sides AB and AC equal to each other and solve for the unknown variable.
4x + 1 = 2x + 23
You should get that x = 11.
Substitute x = 11 into the expression for side BC to solve for the length of that side.
f(11) = 3(11) - 8
f(11) = 25
Thus, length of side BC is 25 units.
Use this way of solving for all your future questions. It's really simple :)
6(3+4) is the right answer because when you distribute you get 18+24.
Hope this helps!!
Answer:
the number is 5
Step-by-step explanation:
We have to find the equation to solve the problem.
Let the number be x
lets write one more than seven times the difference of a number and 4 in mathematical form
1. Difference of number and 4 will be written as x - 4
now
2. seven times the difference of a number and 4 will be written as
7*( x - 4)
3. one more than seven times the difference of a number and 4 is expressed as
1 + 7*( x - 4)
_____________________________________________
1 + 7*( x - 4) is equal to twice the difference of the number and 1
4. difference of the number and 1 is x - 1
5. twice the difference of the number and 1 is 2*(x-1)
Thus,
1 + 7*( x - 4) = 2*(x-1)
=> 1 + 7x - 28 = 2x -2
=> 7x - 27 = 2x - 2
adding 27 both sides
=> 7x - 27 + 27 = 2x - 2 + 27
=> 7x = 2x + 25
subtracting 2x from both sides
7x -2x = 2x + 25 - 2x
=> 5x = 25
dividing both side by 5
5x/5 = 25/5
x = 5
Thus, the number is 5 answer
