5 x 6 = 30
The area is 30
0.61 ml. 3.56 mL - 2.95mL = the amount added to the jar
SOLUTION
Step1; Write out the given expression
Sep2: Solve the expression on the left hand side
Then equate to the right-hand side
Therefore
The coefficient is 5
The constant is -3
An = a1 + (n-1)*d
n = term to find = 30
a1 = first term = 20
d = common difference = 2
a30 = 20 + (30 - 1) * 2
a30 = 20 + 29 * 2
a30 = 20 + 58
a30 = 78
sn = (n (a1 + a30)) / 2
s30 = (30(20 + 78) / 2
s30 = (30(98) / 2
s30 = 2940/2
s30 = 1470 <===
V+8*v-3
v+v=2v
8+-3=5
Equation would be: 2v*5 because you cannot combine unlike terms
