Answer:
C. mental set
Step-by-step explanation:
A mental set generally refers to the brain's tendency to stick with the most familiar solution to a problem and stubbornly ignore alternatives. This tendency is likely driven by previous knowledge (the long-term mental set) or is a temporary by-product of procedural learning (the short-term mental set).
Answer:
A, L, F
Step-by-step explanation:
Quadrant ll (2) is the top left one so points A, L, F are in it. Hope this is correct!
Given: PQ=2x-3. if QR=5x+7 and PR=10x-11
To Find: PR
Solution: From the attached diagram, point P, Q and R are co-linear.
Hence, PR = PQ + QR
or, 10x-11 = 2x-3 + 5x+7
or, 10x - 7x = 15
or, x = 5
Now, we shall calculate the value of PR
PR = 10x-11
or, PR = 10× 5 - 11
or, PR = 39
Hence, the required value of PR will be 39.
