Answer:

infinitely many solutions

Step-by-step explanation:

Given

- 3(x - 14) + 9x = 6x + 42 ← distribute and simplify left side

- 3x + 42 + 9x = 6x + 42

6x + 42 = 6x + 42

Since the equation is the same on both sides, then any real value of x is a solution.

That is has infinite solutions

german

Answer:

(E) 27

Step-by-step explanation:

Let the 5 digit palindrome be PQRQP

Since each digit is chosen from 1,2,3 therefore

P can either be 1,2 or 3 which gives us 3 options.

Q can also either be 1,2 or 3 which gives us 3 options

R can either be 1,2 or 3 which also gives us 3 options

So we have 3^3 = 3*3*3

= 27

This means 27 palindromes are possible if they are formed using one or more of the digits, 1, 2, 3.

ziro4ka [17]

Answer:

D) Identifies the transaction and is located at the top right corner of the check

Step-by-step explanation:

The check number on a check is the number located at the top right corner of the check, and it can also be found at the bottom of the check, located in lower right corner after the routing number and the account number

The check number aids in the tracking and identifying bank transactions such as to identify checks that the bank has processed and to know outstanding checks that are yet to be processed.

The check number also aids in balancing of the checkbook.

Therefore, the check number on a check identifies the transactions and is located at the top right corner of the check.

Find the area of the kite
mart [117]

Answer:

Area of the kite = 30 square units

Step-by-step explanation:

The area of a kite is easily gotten when we can recall the formula.

A kite is a quadrilateral with two diagonals.

We'll label the diagonals as D1 and D2.

Area of kite = ½ D1*D2

D1 = 10

D2 = 6

Area = ½ * D1 * D2

Area = ½ * 10 * 6

Area = ½ * 60

Area = 60/2

Area = 30.

Area of the kite = 30 Square unit.

Please always remember to add your units

Enjoy maths!
