First you do 16 times 10 for the base(the square on the bottom), this equals 160.
Then you do 17 times 10 for sides. We have two of these so just add 170 plus 170 which equals 340.
Next use the formula A=bh/2 for the triangle. A=16(15)/2 this equals 240 but since we have two triangles then we don’t have to divide it.
Then add all of your numbers which are 240+160+340 and you get 740.
I hope this makes sense

Nonlinear, linear, nonlinear(Please excuse my grammar)
Step-by-step explanation:
A is nonlinear because it is an exponential function. As we add more X inputs, the change is the Y coordinates increase by a greater and greater amount. As an example, X=1, then Y=3, X=2, then Y=9, etc. B is linear because it is a horizontal line. No matter the X input, Y will remain the same because it is given: y=-5. C is nonlinear because it is a quadratic function. In any quadratic function, the line reaches a vertex before changing directions therefore, not forming a line.

Stanley has two sets of three cards face down on a table. Each set contains: the 2 of hearts, the 5 of diamonds, and the 8 of clubs. He randomly turns over one card from each set.
Find the probability of each event:
a) Both cards are red.
b) The first card is red and the second card is black.
c) Both cards are even numbers.
d) The sum of the numbers is greater than 8.
Which strategy did you use each time?
Please explain your work.`
Answers
Answer:
a =4/9 = Both cards red
b =2/9 = 1st red 2nd black
c =8/12 = 2/3 simplified even numbers
d= 8/12 = 2/3 simplified sum adds to 8
Step-by-step explanation:
a) Both cards are red see b) 2/3 x 2/3 = 4/9
Answer 4/9
b) One of each colour red selected 1st then black
Answer = 2/3 x 1/3 = 2/9
Answer = 2/9
b) workings
(P2)Any colour RED
(P2)= S1: ( 2/3, 2/3, 1/3)
(P2) = S2: (2/3, 2/3, 1/3)
RED = 1 x 2/3 x 1/3 = 2/9 first card and second card BLACK= 1 x 1/3 = 1/3
Final = 2/9 x 1/3 = 2/9
Answer = 2/3 x 1/3 = 2/9
c)
(P3) Even numbers
(P3)= S1: ( 2/3, 1/3, 2/3)
(P3) = S2: (2/3, 1/3, 2/3)
12 events 7 outcomes see chart below as two even numbers added will always be even numbers and so will two odds including 5+5 = 10
Answer = 8/12
d)
(P4 ) Numbers that multiply to greater than 8
2 + 2 = 4
2 + 2 = 4
2 + 5 = 7
2 + 8 = 10
5 + 5 = 10
5 + 5 = 10
5 + 2 = 7
5+ 8 = 13
8 + 8 = 16
8 + 8 = 16
8 + 2 = 10
8 + 5 = 13
= 12 events either card and 8 opportunities
Answer = 8/12 simplified = 2/3
