Answer:
the surface area is 133cm.
7 x 7 is 49
7 x 6 is 42.
42 divided by 2 is 21.
21 x 4 is 84
So 84 + 49 is 133.
1 g/ml is 8.3454 lbs/gal. So you multiply 1.09 into 8.3454 and your answer is 9.1 lbs/gal
Y = |x| = x if x ≥ 0, -x if x < 0
absolute value can be interpreted as a function that does not allow negative real numbers, forcing them to be positive (leaving 0 alone). if the input x is more than or equal 0, then x stays positive so there is no need to do anything: "x if x ≥ 0".
if the input is less than 0, then it is an negative number and needs a negative coefficient to negate the negative: "-x if x < 0"
example: if x = -3, then it will take the "-x if x < 0" piece resulting in y = -(-3) = 3, which is what |-3| does
if x = 1, it will take the "x if x ≥ 0" piece and just have y = 1 which is what |1| does.
for x = 0, it will take the "x if x ≥ 0" and just have y = 0 which is what |0| does
Answer:
x=45/2
Step-by-step explanation:
2x-6=39
2x=39+6
2x=45
x=45/2
