Answer:
9) 3rd side = 2x+2y
10) 5a^2 + 6a - 3
Step-by-step explanation:
9) 10x+5y - ( 3x+ 4y) = 7x + y
7x + y - ( 5x - y ) = 2x + 2y
10)
Answer:
Step-by-step explanation:
given that two cards are drawn, without replacement, from a standard 52-card deck.
a) Both cards are red
Here there are 26 red cards and 52 total cards.
Probability = 
b) Both cards are the same color
i.e. either both are red or both are black
Hence probability = twice of part a
= 
c) The second card is a queen, given that the first card is an ace.
If first card is an ace remaining are 51 cards with 4 queens\
So prob = 4/51
It is a positive slope and the slope is positive 2/3, to find the slope you do rise/run between two point, for example, to go from (2,-5) to (5,-3) you go up 2 squares and run 3 squares, making ur slope 2/3
Answer:
B
Step-by-step explanation:
The volume (V) of a pyramid is calculated as
V =
area of base × perpendicular height (h)
area of square base = 12 × 12 = 144 units² and h = 8, hence
V =
× 144 × 8 =
= 384 units³ → B
