An expression is shown below: Please help! 4(m + 3 + 5m)

part A: Write two expressions that are equivalent to the given expression shown above.

Part B: show that one of your expressions in part A is equivalent to the given expression using algebraic properties. Please show which properties you used by listing them.

Part C: show that your other expression from part A is equivalent to the given expression by substituting a number for m.

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.

the answer is stop cheating on things stoopid

step-by-step explanation:

im eatin up the 44

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
