P(S+B)=0.5*0.6=0.3
Step-by-step explanation:
Use the multiplication rule if the events are independent.
Well put 34 units on the left vertically and 17 units on the bottom hoizontially... fill it up and count how many you have
Answer:
(7x+2)(3x-1); (5x+4)^2 or (5x+4)(5x+4);
Step-by-step explanation:
formula to find area is L* W = A ; meaning length multiplied by width equals to the area.
21.
using the formula to find area...
l*w=a
(7x+2)(3x-1) would be your answer
btw, don't put the "=a" at the end, since it's an expression :))
22.
since the problem states that it's a square, you can just say either...
(5x+4)^2 or (5x+4)(5x+4) not sure which one your teacher accepts
Answer:
B should be the answer but it could but C
The different between n and 15 is 5 in an algebraic expression would be n-16=5
