Answer:
(5x+4)^2
Step-by-step explanation:
The numerical expression for the verbal expression is 18 ÷ (2+7).
Given,
Verbal expression = Eighteen divide by the sum of two and seven
we know that ,
We can write any verbal expression to numerical expression by using playing with numbers.
Playing with numbers:
Playing with numbers involves activities like arranging the numbers, understanding , finding out whether a given number is a factor of another number or a multiple of another number, and understanding the properties of factors and multiples
Now, According to question
Eighteen divided by the sum of two and seven
18÷(2+7)
Therefore,
The numerical expression is 18÷(2+7).

Answer:
7) is not an arithmetic sequence...
9) 
10) 
Step-by-step explanation:
7 is not an arithmetic sequence because consecutive terms of the sequence do not have a constant common difference.
9 has a first term of 0.5 and has a common ratio of 4 (the quotient between the second term and first, then third term and second, etc.). Thus, your equation is
10 has a first term of -0.25 and has a common ratio of -8 (the quotient between the second term and first, then third term and second, etc.). Thus, your equation is
3(6/8−1/2)+0.25
Rewrite 6/8 and 1/2 to have common denominators:
1/2 = 4/8
Now you have
3(6/8−4/8)+0.25
Simplify inside the parenthesis first:
3(2/8) +0.25
2/8 reduces to 1/4"
3(1/4) +0.25
Multiply 3 and 1/4:
0.75 + 0.25
Now add to get the final answer, which is 1.00
