Choose the best definition for the following term: algebraic expression. a mathematical expression consisting of a constant that is raised to some power. the number or value being raised to a power. a number or group of numbers that are added, subtracted, multiplied or divided. a number, a variable, or group of numbers and variables that are added, subtracted, multiplied or divided

D.A number, a variable , or group of numbers and variables that are added, subtracted, multiplied or divided.

Step-by-step explanation:

We have to find the best definition of algebraic expression

Algebraic expression:It is that expression which is   made from integer constants,variables and algebraic operations includes addition, subtraction, division , multiplication and exponentiation by an exponent that is a rational number.

For example:

Therefore, correct definition is given by

A number, a variable , or group of numbers and variables that are added, subtracted, multiplied or divided.

D.A number, a variable , or group of numbers and variables that are added, subtracted, multiplied or divided.

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
