A prime number is a number that has no other factors except 1 and itself. For example, the number 12 can be broken down into 1x12, 2x6, and 3x4, therefore 12 is not a prime number. However, the number 13 has no other factors except 1x13, therefore it IS a prime number. To answer this question, 19 and 19 could be used. Or 31 and 7. Or 33 and 5.

Answer:

Area of shaded region=41 square feet

Area of non shaded region= 87 square feet

Step-by-step explanation:

As, Shaded area is made of different shapes including two rectangles and one triangle

So,

Area of shaded region,

$=(8\times2)+(10\times 1)+(\frac{1}{2}\times 3\times10)\\\\ =16+10+15=41 \quad \text{square feet}$

Area of non shaded region=total area of rectangular region-Shaded region

$=(16\times 8)-(41)\\=128-41\\=87 \quad \text{square feet}$

QUESTION ATTACHED PLZ HELP NEEDED

saw5 [17]

Y = a (x + 3)² - 1

Let's take the point (-1;3)

3 = a ( -1 + 3)² - 1
3 = 4a - 1
4a = 4

Therefore a = 4/4 = 1

(x+3)² - 1
= x² + 6x + 9 - 1
= x² + 6x + 8

The answer would be y = x² + 6x + 8.

Hope this helps !
