In the PQ4R method, one of the 4Rs stands for "Review." This step involves revisiting the material after initial engagement to reinforce understanding and retention. By reviewing the content, learners can better consolidate their knowledge and identify any areas that may require further clarification or study. Overall, this process enhances long-term memory and comprehension.
4r-48 = -44
To simplify the expression (4r \cdot r), you multiply the coefficients and combine the like terms. This results in (4r^2). Thus, the simplified form of (4r \cdot r) is (4r^2).
s = -2 -4r
If you mean: 10+4r = 30 then it works out that r = 5
-13
-2=4r+s s=-4r-2 or s=-(4r+2)
4r-48 = -44
recover is one of the principles of the 4r principle
4r + 4 = 5r 4r - r = 3r 4r x r = 4r^2 4r/r = 4
To simplify the expression (4r \cdot r), you multiply the coefficients and combine the like terms. This results in (4r^2). Thus, the simplified form of (4r \cdot r) is (4r^2).
It is 4r + 12s
If 36 = 4r, r = 9
4r + 13 = 57subtract 13 from both sides:4r + 13 - 13 = 57 -134r = 44divide both sides by 4 to solve for r:4r/4 = 44/4r = 11
s = -2 -4r
It is in its simplest form: 4r+r = 5r
4r + 8rs + 28r 4r is a factor of every every term so the expression can be written 4r(1 + 2s +7) NOTE : The original expression can be simplified to 8rs + 32r and thus the factored expression becomes 4r(2s + 8).
Since 4R and R both contain a like term (R), you can combine them: 5R would be 4R plus R simplified
