Answer: 20%

Step-by-step explanation:

According to the  zookeeper ,

The predicted weight of the newborn lion = 2.8 pounds

The actual weight of the newborn lion = 3.5 pounds

Now , the zookeepers's percent error = \dfrac{|Predicted-actual|}{actual}\times100

=\dfrac{|2.8-3.5|}{3.5}\times100\%\\\\=\dfrac{|-0.7|}{3.5}\times100\%\\\\=\dfrac{0.7}{3.5}\times100\%\\\\=\dfrac{100}{5}\%=20\%

Hence, the zookeepers's percent error = 20%.

Another possible expression is to sum 3 times w, that is w + w + w (it's equal to 3*w).

Bess [88]

Answer:

w=2  w = -9

Step-by-step explanation:

w^2 + 7w - 18 = 0

We can factor this equation

What 2 numbers multiply to -18 and add to 7

9*-2 = -18

9+-2 = 7

(w-2) (w+9) = 0

Using the zero product property

w-2 = 0    w+9 =0

w=2  w = -9
