Answer:
41.13 centimeters (rounded to 2 decimal places)
Step-by-step explanation:
The perimeter is the sum of all sides of the figure.
This figure consists of two semicircular lines (right and left) and two lines (top and bottom). We add up all of them and find the perimeter of the figure.
The expression for (r-s)(x) is found by subtracting s from r. That difference is
. The expression for (r+s)(x) is found by adding them, which is
. Now we are told to evaluate (r*s)(x) which means they want us to multiply those and state the "new" expression that results.
. There you go!
Answer:
79
Step-by-step explanation:
(58+88+80+70+ x)/5=75
75*5=296x
375=296x
x=375-296
x=79
ans is b...multiply eqn 1 by -2 and eqn 2 by 3
=》 -6x + 10y = 4...eqn 3
=》 6x + 3y = 9...eqn 4
add eqn 3 and 4...
=》13y = 13
=》y =1 and x = 1
