Answer:
P = 12m
A = 6m^2
Step-by-step explanation:
Perimeter is the sum of all the lengths of a shape. The lengths of the triangle are given as 3m, 4m, and 5m, so to find the perimeter we just need to add them all together. 3+4+5=12, so the perimeter of the triangle is 12m.
The area of a triangle is found by multiplying its height by its base and then dividing the result by 2. The height of the triangle is not given, but the side lengths (3,4 and 5) indicate that the triangle is a right triangle. This means we can use the middle length as the height and the shortest length as the base.
So, the height of the triangle is 4m, and the base is 3m, so to calculate the area:
(3x4)/2=12/2=6m^2.
The area of the triangle is 6m^2.
Hope this helped!
(x - 5)(x + 5)(2x - 1)
= (x ^ 2 - 25)(2x - 1)
= 2x ^ 3 - x ^ 2 - 50x + 25
Answer:
x > -2
Step-by-step explanation:
First, you simplify both sides of the inequality by combining like terms
Then, you add 6x to both sides in order to isolate x (bring all the Xs to one side)
Lastly, you divide by 8 in order to cancel out 8x solve for x. Since 8 is not a negative number, you DO NOT flip the sign.
Your answer would be “a”.
In order to receive a positive solution in the following equation, you must include a double negative to have them cancel each other out and come up with a positive value. Sorry if this is confusing it’s easier to explain this process in person rather than online but I hope this helps anyways :)
