Find the solution to each equation mentally or use your calculator. (do the opposite of the number on the left side of the equation) A: 30+a=40

B: 500+b=200

C: −1+c=−2

D: d+3,567=0

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..

i really dont know

step-by-step explanation:

if i put something wrong your not gonna like it so rather not say nothing.

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
