3. Which of the following expressions is equivalent to the expression 21−6x for all values of x ? 5−2(8−3x) 6+3(5−2x) 25−(4−6x) 3(4−2x)−9 7(3−2x)−8x : 6+3(5−2x) Option (B) is correct. Using the distributive property, 6+3(5−2x)=6+15−6x=21−6x. None of the other selections is equivalent to this. 5. A right circular cylinder with base B is shown. If a plane that is neither parallel nor perpendicular to base B passes through the cylinder, which of the followi...

2 components of conjuctiva - Bulbar conjuctiva (covers the anterior eyeball) Palpebral conjuctiva (lines the eyelids) 20/30, what does this mean? - First number indicates the distance of the patient from the chart. The second indicates the distance at which a normal eye can read the line of letters. So 20/30 means the pt can read at 20 ft. what a normal eye can read at 30 ft. Acommodation - Increased convexity of lenses. Brings near objects into focus. Anisocoria - inequality in the diamet...

C. asking probing questions about the total number of counters each student has. A kindergarten teacher observes as a small group of students practice comparing numbers and quantities using manipulatives. Each student has four counters. One student's counters are spaced farther apart than the other students' counters, and several members of the group claim that student has more counters than everyone else. The teacher can build on the students' understanding of counting and cardinality by: ...
