the diagram shows an isosceles triangle. all measurements are in cm.
3x-5 19-x
2x
work out the perimeter of the triangle
Answer: 38
Solution: An isosceles triangle has two equal sides: 3x - 5 and 19-x.; 3x - 5 = 19 - x; 4x = 24; x = 6
Let's check it out: 3(6) - 5 = 13; 19 - (6) = 13; 2(6) = 12
Two equal sides are 13 and base 12
Perimeter is 13 + 13 + 12 = 38 units
Answer is: 38
The perimeter of the given isosceles triangle is 38 cm.
What is the perimeter of an isosceles triangle?The perimeter of an isosceles triangle refers to the addition of all the three sides of the triangle. Since the base angles of an isosceles triangle have two angles and two sides equal;
We can say that the perimeter of an isosceles triangle is:
P = 2a + b
where;
a = sides of the base anglesb = third side3x - 5 = 19 - x
3x + x = 19 + 5
4x = 24
x = 24/4
x = 6
The perimeter of the isosceles triangle is:
= 3x - 5 + 19 - x + 2x
= 3(6) - 5 + 19 - 6 + 2(6)
= 18 + 8 + 12
= 38 cm

f(x) = 4x2 + 5x - 3
g(x) = 4x2 – 3x2 + 5
Find (f +g)(x).
Answer:
5x + 12
Step-by-step explanation:
simplify f(x) and g(x)
g(x) = 4*2 -3*2 +5
g(x) = 8 -6 + 5
g(x) = 7
and
f(x) = 4*2 + 5x -3
f(x) = 8 + 5x - 3
f(x) = 5x + 5
So (f + g)(x) = f(x) + g(x)
(f + g)(x) = (5x + 5) + (7)
(f + g)(x) = 5x + 12

do I add multiply, add, subtract ? I need help!
Answer:
x=35
Step-by-step explanation:
you are going to want to subtract. the best thing about triangle angles is that they all add to equal 180º no matter what. so what you can do is subtract the given angles from 180. so 180-80-65. which gives us 35.
Hope this helps!
Answer:
I believe you add, degrees in triangles are 180 so 80+65= 145. 180-145 is 35

An elevator moves from the top of a tall building to the ground floor without stopping. Explained why a blindfolded person in the elevator may believe that the elevator is not moving at all. Can the person tell when the motion begins or stops?Explain
Answer:
Part A
The motion of an elevator in a building is mechanically controlled by electrical powered devices and therefore, the motion of an elevator between start and stop is uniform motion without acceleration and therefore, a person in a moving elevator will not experience a force, therefore a blindfolded person will believe that the elevator is not moving at all
Part B
Yes the person can tell when the elevator begins or stops
When the elevator begins moving, the velocity increases from zero at a rate and the blindfolded person will be able to sense the ground moving further lower under their feet making them feel lighter
Similarly, when the elevator slows down to stop, the initial downward velocity of the elevator is steadily reduced as the elevator decelerates. The blindfolded person will be able to sense the slowing down (braking) of the elevator experiencing an increased upward force from the floor of the elevator, with the feeling of slightly increased weight

What are the coordinates of D, E, and F after a reflection over the y axis? Plot these points on the grid, and label them D′, E′ and F′.
Answer:
D → (-3, 3)
F → (2, -2)
E → (0, 5)
Step-by-step explanation:
Coordinates of a point is given by [tex](x,y)[/tex].
Here, [tex]x[/tex] represents the horizontal distance of the point from origin [tex](0,0)[/tex] and [tex]y[/tex] represents the vertical distance of the point from origin.
Let's take an example of point D,
Horizontal distance of point D from origin [tex]x=-3[/tex] and vertical distance from origin [tex]y=3[/tex]
Coordinates of the point D will be (-3, 3).
Coordinates of the point F will be (2, -2).
Coordinates of the point E will be (0, 5).

A sales item is 20% off. If the final price of the item was $560.00, what was the original price of the item?
Answer:
700
Step-by-step explanation:
price x .80 (100%-20)=560
price=560/.8
price=700
The item's initial cost before taxes is $700.
What is the percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
Given, A sales item is 20% off. If the final price of the item was $560.00
Let "x" be the original price of the item
Since If the final price of the item was $560.00
Thus,
x(1 - 20%) = 560
x(1- 20/100) = 560
x(80/100) = 560
x = 700
therefore, The original price of the item without tax will be $700.
