Answer:

B and D

Step-by-step explanation:

The polynomial x² + 6x - 8 ( from values in first row )

is being evaluated at x = - 5 thus the factor is (x + 5)

If (x + 5) is a factor the remainder = 0

Hence (x + 5) is not a factor since remainder = 12 ≠ 0

When the polynomial is evaluated at x = 5 it's value is 12

The remainder theorem states that f(h) = remainder, hence

f(- 5) = 12 ← remainder

a scale model of the human heart os 196 in. The scale is 32:1, what is the approximate actual size of the heart

Yanka [14]

If it is a 32:1 then the answer is somewhere around 6.125 inches

32 : 1 = 196 : X
32X = 196
X = 196/32
X= 6.125

#2) The Ramy family went

suter [353]

If there were only sandwiches bought, there would be 15, if there were only salads bought there would be 20. There’s probably more than one possibility, but that’s the best I can do, considering how long it’s been since I’ve done this type of problem. I’m all the way to learning determinants, so I really have to think to remember these. Sorry in advance if this doesn’t help at all, I’m not the best at this, but I can still try.
