Answer:
second option
Step-by-step explanation:
The perimeter is the sum of the 3 sides of the triangle
Given
hypotenuse = x
and
the combined length of the legs = 2x , then
perimeter = x + 2x
OK,
this is an equilateral triangle, and by the indicators on the lines, we know the bottom angles have to be the same
we also know that angles in a triangle sum to 180
with this information we can work out the angle x
180 - 24 = 156
156/2 = 78
The answer is 78
Answer:
B
Step-by-step explanation:
The x values are bring reflected across the y-axis. The x values are now negative to reflect the figure.

Answer:
The correct answer is option A. 18x + 15
Step-by-step explanation:
It is given an expression in variable x,
5(4x + 3) - 2x
<u>To simplify the given expression
</u>
5(4x + 3) - 2x = (5 * 4x) + (5 * 3) - 2x (open the bracket)
= 20x + 15 - 2x
= 20x - 2x + 15
= 18x + 15
Therefore the correct answer is 18x + 15
The correct option is option A. 18x + 15
