I hope the answer will help you.
If x- 7 = 14 then X = 21. so 21-2= 19. :)
Assuming There is ONLY ONE CORRECT ANSWER,
The probability of her guessing the answer without ruling out the choices is 1/5.
if 3 choices are ruled out, then 1 out of the remaining two is right, which gives the probability 1/2
now, 1/5 = 20% , while 1/2 = 50%.
Therefore her probability of getting the correct answer improves by 30% [ not much in a REAL test though :P ]
This is the difference of 2 squares
square root of a^6 = a^3
and square root of 25 b^2 = 5b so we get
(a^3 + 5b)(a^3 - 5b)
Thats the answer
Answer:
-1960
Step-by-step explanation:
The expression on the left expands to ...
(4x -7)² = (4x)² +2(4x)(-7) +(-7)² = 16x² -56x +49
Matching coefficients, you have ...
Then the expression c(b+a) evaluates to ...
49(-56+16) = 49(-40) = -1960
