Which phrase correctly represents the algebraic expression 3t? A. The sum of three and a number.
B. The product of three and a number.
C. The quotient of three and a number.
D. The difference of three and a number.

B

Explanation: When a number is directly followed by a variable (ex. 10y), it indicates multiplication. So in this case, when you dissect the expression 3t, it becomes 3*t. For both addition and subtraction, it would be the normal format: 3+t and 3-t. For division it would be 3 over t (fraction format).

Step-by-step explanation:

here x is hypotenuse because it is the side opposite to largest angle.

12 and 15 are the two other legs of the triangle .so let them be a and b rectively . And let hypotenuse be c.

according to the pythagoras theorem

a^2 + b^2 = c^2

12^2 + 15^2 = x^2

144 + 225 = x^2

369 = x^2
