The sum of two sides of a triangle must be greater than the third side
1) 5+9>14
14>14 It is incorrect so you can’t have these lengths
2)7+7>15
14>15 X
3)1+2>4
3>4 X
4)3+6>8
9>8
6+8>3
14>3
8+3>6
11>6
So the fourth choice is correct
hi ! so the answers are below ...
<h3>1. we need to add both angles to find angle QST</h3><h3> <u>5</u><u>2</u><u> </u><u>+</u><u> </u><u>4</u><u>7</u></h3><h3> <u>=</u><u> </u><u>9</u><u>9</u></h3>
<h3>2. since the angles are on a straight line, to find the angle NPM we need to subtract the given angle with 180⁰ since the total of a straight line is 180⁰ ( hope you understand )</h3>
anyways...
<h3> <u>1</u><u>8</u><u>0</u><u> </u><u>-</u><u> </u><u>7</u><u>9</u></h3><h3> <u>=</u><u> </u><u>1</u><u>0</u><u>1</u></h3>
hope that helped and let me know if you have any more questions :)
The question does not make sense.
The commutative property applies to addition and multiplication, not addition and subtraction.
The commutative property does not apply to subtraction or division because in those operations, the order of the numbers makes a difference, whereas in addition and subtraction the order does not make a difference.
For example:
Addition
5 + 4 = 9
4 + 5 = 9
5 + 4 = 4 + 5
Changing the order of the 4 and the 5 gives the same answer.
The commutative property does apply to addition.
Multiplication
5 * 4 = 20
4 * 5 = 20
5 * 4 = 4 * 5
Changing the order of the 4 and the 5 gives the same answer.
The commutative property does apply to multiplication.
Subtraction
5 - 4 = 1
4 - 5 = -1
5 - 4 is not equal to 4 - 5
Changing the order of the 4 and the 5 gives a different answer.
The commutative property does not apply to subtraction.
Division
5/4 = 1.25
4/5 = 0.8
1.25 is not equal to 0.8.
Changing the order of the 4 and the 5 gives a different answer.
The commutative property does not apply to division.
Answer:
5. A) two solutions
6. one solution
Step-by-step explanation:
5. A graph shows the curve has two x-intercepts, so two solutions. You can also figure this by looking at the discriminant:
b^2 -4ac = (7)^2 -4(-4)(8) . . . . a positive number
When the discriminant is positive, there are two real solutions.

6. The equation factors as ...
0 = 3(x +3)^2
This will have one real solution at x=-3.
