Answer: The word phrase for this expression is the last option, "The sum of the quotient of d and 5 and 2." d is being divided by 5, so we would use "quotient of d and 5" for that part, and then we would add the "sum" because d/5 is being added to 2.

Answer:
an = 39 +4(n -1)
Step-by-step explanation:
The formula for the general term of an arithmetic sequence is ...
an = a1 +d(n -1)
Here, the sequence has first term a1 = 39 and common difference d = 43-39 = 4. So, the general term is ...
an = 39 +4(n -1)
Answer:
the answer is 72 un. sq.
Step-by-step explanation:
Answer:
x=2/5, y=11/5
or x=−1y = 2
Step-by-step explanation:
Substitute y=3x+1 in x2+y2=5 to obtain
x2+(3x+1)2=5 ⇒ 10x2+6x−4=0
Hence
5x2+3x−2=0 ⇒ 5x2+5x−2x−2=0 ⇒5x(x+1)−2(x+1)= 0 ⇒ (5x−2)(x+1)=0
Hence
either
x=2/5, y=3×2/5+1=11/5
or x=−1, y=3×(−1) +1 = −2
