1. Consider the trinomial, x^2 - 9x + 14 (a) Is x + 7 a factor of the trinomial? Explain your reasoning.
(b) Write the factored form of the trinomial.

Try Your Best! I hope you figure it out! I promise! :)

Step-by-step explanation:

a. no

Step-by-step explanation:

if you do part b, you will see why part a is no.

if you aren't quick with the FOIL method, then here is a tip. you see that the last number is 14, so think of 2 numbers that make 14 when multiplied together. also, see if those 2 numbers when added or subtracted together create the middle number, in this case 9.

you think oh 7 and 2 mulitpled equal 14, and oh when added they make 9.

for foil method, you see 7 and 2 must make 9, but actually, a -9. so you would see quickly that foiling would get you

(x-7)(x-2), which would get you -7x -2x = -9x, and then -7 × -2 = positive 14.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
