Step-by-step explanation:
Length of arc
Answer:
1. An algebraic expression of three non-zero terms only is called a trinomial.
2. like terms
3. x=49
4. positive
C and E, evaluate the numbers outside of the parenthesis to the inside
X would equal 57 if 52 replaces x then 3+52 is 55 and 55+2 equals 57.
It is a linear simple equation for one unknown, lets solve it!
-4.2x + 31.5 = -65.1
we can easily get rid of decimals if we multiply the whole equation times 10:
<span>-42x + 315 = -651
</span>-42x = -651 - 315 = -966
x = 966/42
x = 23
that is the solution
