Answer: 8:14
Step-by-step explanation:
Your answer would be 8:14, as Steven answered 8 questions incorrectly along with the total number of problems being 14 when you add his correct answers with his incorrect ones: "6+8"
Option D is a linear equation, so it represents a direct linear variation.
Hope this helps!
The formula for the volume of a pyramid is,
V=1/3Bh
Since the base of the pyramid is a square, the base area is 11^2
which equals 121 sq. units
So, substitute 121
for B
and 6 for h, in the formula.
V=1/3(121)(6) = 242 cu. units
Or alternatively 1/3(11^2)(6) = 242 cu. units
The equation will simplify to a linear equation in n, which can be solved to find n.
n² +6n +8 = (n -2)(n -9) . . . . . . we assume this is your intent
n² +6n +8 = n² -11n +18 . . . . . . expand the right side
17n = 10 . . . . . . . . . . . . . . . . . . . add 11n -8 -n² to both sides
n = 10/17 . . . . . . . . . . divide by the coefficient of n
The number that makes the equation true is n = 10/17.
