Alex didn't answer it correctly, because if you see the part where it says -5x - (-7...
it has two minus signs, one in front of the parantheses, and one behind it.
Since they cancel each other, the 7 would be positive.

A triangle has sides with lengths of 21m, 28m, and 49m. Is it a right triangle?
Answer:
To find : If 21m, 28m and 49m form a right angle or not.
Logic : To find if this triangle is a right angle, we can use the Pythagoras Theorem, which states that the square if the longest side should be equal to the square of the sum of the other two sides.
The name of the longest side is called the hypotenuse, while the others are called legs or one is the perpendicular and the other the base.
Proof : [tex]h^{2} = p^{2} + b^{2}[/tex]
=> [tex]49^{2} = 28^{2} + 21^{2}[/tex]
=> 2401 = 784 + 441
=> 2401 ≠ 1225
Therefore these side lengths cannot be the lengths of a right angled triangle.

Answer:
The difference in cost per mile is $0.94.
Step-by-step explanation:
Uber
7x = 20.37
x = $2.91 per mile
Lyft
4y = 15.4
y = $3.85 per mile
3.85 - 2.91 = 0.94
Hello.
To find the difference in cost per mile, divide the cost by the amount of miles, then subtract the two answers.
20.37 / 7 = 2.91 (cost per mile {cpm} for Uber)
15.40 / 4 = 3.85 (cost per mile {cpm} for Lyft)
3.85 - 2.91 = 0.94
The difference in cost per mile is $0.94

Write an equation for a line that is parallel to y = -4x + 2 and passes through the point (-2, 5).
Answer:
y = -4x - 3
Step-by-step explanation:
y = -4x + 2
Substitue Y and X and turn 2 into b(or y intercept)
5 = -4(-2) + b
Solve for b
5 = 8 + b: subtract 8 from both sides
-3 = b
substitute for 2 with same slope(to keep parrallel)
y = -4x - 3

11. Six times a certain number less 31 is the same as 10 subtracted from
Ehree times the number. Write the equation and find the number.
Answer:
The number is 7Step-by-step explanation:
x - a certain number
6x - - six times the number
6x-31 - six times the number less 31
3x - three times the number
3x-10 - 10 subtracted from three times the number
so the equation:
6x - 31 = 3x - 10
+31 +31
6x = 3x + 21
-3x - 3x
3x = 21
÷3 ÷3
x = 7
Check: 6•7-31=42-31=11; 3•7-10=21-10=11

Solution :-
As per provided information in the given question, we have been given that the Radius of a cylinder is 5 meters. The height of a cylinder is 8 meters. We have been asked to find the volume of a cylinder.
To calculate the volume of a cylinder, we will apply the formula below :-
[tex] \bigstar \: \: \: \boxed{ \sf{ \: \: Volume_{(Cylinder)} = \pi r^2 h \: \: }}[/tex]
Substitute the given values into the above formula and solve for Volume :-
[tex]\sf:\implies Volume_{(Cylinder)} = \pi r^2 h[/tex]
[tex]\sf:\implies Volume_{(Cylinder)} = (3.14)(5 \: m)^2(8 \: m)[/tex]
[tex]\sf:\implies Volume_{(Cylinder)} = (3.14)(25 \:m^2)(8 \: m)[/tex]
[tex]\sf:\implies Volume_{(Cylinder)} = (78.5 \:m^2)(8 \:m)[/tex]
[tex]\sf:\implies\bold{Volume_{(Cylinder)} = 628 \: m^3}[/tex]
Therefore :-
The volume of a cylinder is 628 m³.[tex]\\[/tex]
