We have 4(x^2 - 2x + 4) - 7 = 4x^2 - 8x + 16 - 7 = 4x^2 - 8x + 9;
So, 4x^2 - 8x + 9 = <span>ax^2+bx+c
;
The value of b is -8.</span>
7 1/4
that is the numerical difference between the two
I did the problem myself and my teacher always said thatif you don't get the exact answer then round to the closest one. The answer that i got was 31,808.6, the closest one to that would be letter C.
Answer:
True
False
True
Step-by-step explanation:
The value B is 7. If we apply B=7 the answer is 17 for the expression 17×
Step-by-step explanation:
The given expression is 17×
Step:1
Form an equation from given data,
17×
= 17..............................(1)
(∵ product equal to 17)
Step:2
Check for alternatives by apply the value of B in eqn (1)
Assume be value of B for check the equation
B=1
Equation becomes,
17×
= 2.4286 ≠ 17
Take, B=2,
17×
= 4.8571 ≠ 17
Take, B=3,
17×
= 7.2857 ≠ 17
similarly,
B=7,
17×
= 17 (∵ The product equals to 17)
Result:
So, the answer for B is 7.
