First, we should calculate the areas separately.
4x8=32
5.6 x 4 = 22.4/2 = 11.2
4.5x4=22 22/2=11
4x8=32
32+11+32+11.2
64+22.2=86.2
So 86.2 ft2
Hope this helped. ^^
h=20w
in one week hector works 20 hours
in two hector works 40 etc
h = hours and w = weeks. the money is just extra information.
h=20w works because if it has been two weeks we substitute the w with the number 2 and can solve
h=20(2)
h=20x2
h=40
This proves that the equation is true
Theorem
In a triangle, the measure of an exterior angle equals the sum of the measures of its two remote interior angles.
x + y = z
4n - 18 + n + 8 = 133 - 6n
5n - 10 = 133 - 6n
11n = 143
n = 13
z = 133 - 6n = 133 - 6(13) = 133 - 78 = 55
Answer: C. 55
X=4. Hope this is the one you wanted me to answer.
