Step-by-step explanation:
-15/(-3)
When dividing a negative by a negative, the negatives cancel out, so you're left with 15/3.
15/3 is 5.

which of these shapes is a quadrilateral that has 4 angles that are 90°?
Answer:
Rectangles
Step-by-step explanation:
A rectangle is a quadrilateral with 4 right angles (90°). In a rectangle, both the pairs of opposite sides are parallel and equal in length.
In a quadratic function, recall that the discriminant D = b2 - 4ac. For which function is it true that a < 0 and D = 0?
Answer:
If D = 0, then the quadratic equation has 1 solution x = − b/2a
Step-by-step explanation:
If we have a quadratic equation x² +3x-4= 0
Then the corresponding values of a= 1, b=3, c= -4
Finding the discriminant gives
D= b2 - 4ac.
D= 3²- 4(1) (-4)
D= 9 + 16
D= 25
Here a> 0
But if a< 0 e.g a= -1
D= b2 - 4ac.
D= 3²- 4(-1) (-4)
D= 9 - 16
D= -7
Here a < 0 so we get the answer -7 < 0
D= b2 - 4ac.
D= 4²- 4(-1) (-4)
D= 16 - 16
D= 0
Here a< 0 and b= - c so that D= 0
When D < 0 roots do not exist.
If D = 0, then the quadratic equation has 1 solution x = − b/2a
This can be found out by using the quadratic formula
x= -b±√b²- 4ac/ 2a
But D= 0
x= -b±0/ 2a
x= -b/2a
24 – (-14) = ______
-9 · -5 = ______
31 + x = 15 x = ______
2 x + 5 = 15 x = ______
Step-by-step explanation: (Answers in bold )
24-(-14) using the keep change change rule you get 24 +14 = 38
-9*-5 =45 (negative times a negative = a positive )
31+x=15x subtract x from both sides
31=14x divide by 14
31/16 ---or---> 2.21
2x+5= 15x subtract 2x from both sides
5=13x divide by 13
5/13 or-------> 0.38

Answer:
x^2 - 9
Step-by-step explanation:
The square root of the quadratic equation [tex](x^2 -6x+ 9)[/tex] if x<-3 would be equal to (x-3).
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
The given quadratic equation is
[tex](x^2 -6x+ 9)[/tex]
We have to find the square root of the quadratic equation
[tex]\sqrt{(x^2 -6x+ 9)} \\\\\sqrt{(x^2 -3x-3x+ 9)} \\\\\sqrt{x(x-3)-3 (x-3)} \\\\\sqrt{(x-3) (x-3)} \\\\\sqrt{(x-3)^2} \\\\(x-3)[/tex]
Thus, the square root of the quadratic equation [tex](x^2 -6x+ 9)[/tex] if x<-3 would be equal to (x-3).

what is the probability you roll doubles on two 6 sides dice
please show work
Answer:
1/6
Step-by-step explanation:
We can start by determining all the different combinations we can get.
We are using 6 sided dices, so we have a chance of getting 6 different numbers for each dice.
If we only have 1 dice, the our possible values would be:
1, 2, 3, 4, 5, 6
However, we have 2 dices. As such, our combinations have been multiplied, and now our possibilities are:
(1 , 1) , (1 , 2) , (1 , 3) , (1 , 4) , (1 , 5) , (1 , 6) , (2 , 1) , (2 , 2) , (2 , 3) , (2 , 4) , (2 , 5) , (2 ,6), and so on for 3, 4, 5, and 6
We can find the number of combinations by simply multiplying the amount of possible values for each dice.
Since both dices have 6 possible values, we multiply 6 by 6, and the amount of possible combinations is 36.
Now, let's determine the possibility for getting a double.
First, let's determine how many doubles we can get:
(1 , 1) , (2 , 2) , (3 , 3) , (4 , 4) , (5 , 5) , (6 ,6)
There are 6 different combinations for rolling a double.
So, our probability of rolling a double on two 6 sided dices is 6 out of 36
We can simplify that to 1 out of 6.
So the probability of rolling a double on two 6 sided dices is 1/6

What is the perimeter of the rectangle?
Answer:
10 feet
Step-by-step explanation:
Perimeter of rectangle = 2l+2b
Area of the rectangle = l x b
Area of the rectangle = 4 square feet
possible factors of 4 = 2x2/4x1
So sides of the rectangle are 4 & 1 as 2&2 would make it a square
So perimeter= 2x4+2x1
= 8+2
= 10 feet

Triangle Inequality Theorem: The sum of the lengths of any two sides of a triangle is greater than the length of the third side. Can these numbers be the length of the sides of a triangle? Show the math to prove your answer. Then circle YES or NO. 1) 8,9,10 2) 1, 1, 2 3) 6,9,8 yes or no yes or no yes or no
Answer:
1) yes 2) no 3) yes
Step-by-step explanation:
The lengths of the two shorter sides must be greater than the length of the longest side.
1) 8 + 9 > 10 yes
2) 1 + 1 = 2 no
3) 6 + 8 > 9 yes
The lengths which can be side of triangle are:
8, 9, 106, 9, 8Apply the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
1. 8, 9, 10:
The sum of the lengths of the two smaller sides is 8 + 9 = 17 > 10
Therefore, these numbers can be the lengths of the sides of a triangle.
2. 1, 1, 2:
The sum of the lengths of the two smaller sides is 1 + 1 = 2.
No, 2 is equal to the length of the longest side.
So these numbers cannot be the lengths of the sides of a triangle.
3. 6, 9, 8:
The sum of the lengths of the two smaller sides is 6 + 8 = 14 > 10
Therefore, these numbers can be the lengths of the sides of a triangle.
