Answer:
Only A, the first equation is true.
Step-by-step explanation:
A. (y + 6)(y – 7) + 42 = y² + 6y –7y – 42 + 42 = y² – y. This means A is true
B. (x + 3)(X – 8) = x² + 3x – 8x – 24 = x² – 5x – 24. This means B is false.
Its 7a so the coefficient of a is 7
-- To change a percent into a decimal, move
the decimal point two places this way <== .
33.3% = 0.333 .
-- To change a percent into a fraction, remember
that the symbol ' % ' means ' /100 ' .
33.3 % = 33.3/100 .
That fraction looks ugly, because it has a decimal in the numerator.
That's easy to fix. Multiply top and bottom by 10, and you have
333/1000 .
The second one is the answer: f(4) = 22
A,b,c,d,e,f,g,h I belive that right
