Answer:
n = 6
Step-by-step explanation:
the formula for interior angle is ( n-2)
but we given the measure of one angle, so solve
720 = (n - 2)180
720/180 = (n - 2)
4 = (n - 2)
combine the like terms
4 + 2 =n
6 = n
Step-by-step explanation:
function is when the x- intercept does not repeat the answer is D because the numbers didn't repeat
Answer:
41.13 sq m
Step-by-step explanation:
area of square = 4² = 16
there are two quarter-circles which equals one semicircle
area of semi-circle is πr²/2
A = 4²π/2 = 8π = 25.13
add together: 16 + 25.13 = 41.13
Answer:
length: 23 m; width: 11 m.
Step-by-step explanation:
The perimeter of a rectangle is twice the sum of its length and width, so that sum is 34 m. Then you can write two equations in length and width:
l + w = 34
l - w = 12
Adding these together gives you ...
2l = 46
l = 23 . . . . . . divide by 2
Then the width is
w = 23 -12 = 11
The length and width are 23 m and 11 m, respectively.
