Answer:
39
Step-by-step explanation:
square= lw
triangle= 1/2lw
s=9
triangle=15 divided by 2 times 4=30
you add 30 + 9 which will give you 39
I'm pretty sure that it's b. That's assuming that you find the negative of b^2 and not the square of negative b.
The question is missing some parts. To complete, J is the event of getting a jack and R is getting a red card.
The first question is to look for the P (J) and P (R) =
P (J) = 4/52 = 0.077; since there are only 4 jacks in a standard deck.
P (R) = 26/52 = 0.5; 26 because there are 13 each for diamonds and hearts.
The second question is to describe the event J and R in words. Then look for that event’s probability.
The card is a red jack or the card is red and a jack. P (J and R) = 2/52 = 0/038
The last question is explain why P (J or R) is not equal to P (J) + P (R). Then use the general addition rule to compute for P (J or R).
The event card is red and card is jack are not mutually exclusive meaning two or more events can happen simultaneously. Thus one will count two cards twice unless using the general probability addition formula.
The probability for P (J ∪ R) is:P (J ∪ R) = 2 + 2 + 24 / 52 = 28/52 = 0.0538Or the other solution would be:P (J ∪ R) = 4/52 + 26/52 + 2/52 = 28/52 = 0.0538

Step-by-step explanation:
Perfect square trinomial:
A perfect square trinomial has the following format:
a.
x² – 8x
So 2a = 8, a = 4. Then
The perfect square trinomial is 
b. x2 + 20x +
2a = 20, so a = 10
The perfect square trinomial is 
C.
x² – 16x +
2a = -16, so a = -8.
The perfect square trinomial is 
d. x2 + 9x +
, so 
The perfect square trinomial is

Answer:At a charity fund raiser , adult tickets were sold for 8$ children each and children’s tickets were sold at 2$ each. write an algebraic expression for the total amount raised from the sale of tickets. At a charity fund raiser , adult tickets were sold for 8$ children each and children’s tickets were sold at 2$ each. write an algebraic expression for the total amount raised from the sale of tickets. How much money was raised if the fundraiser sold 238 adult tickets and 375 children’s tickets?
Step-by-step explanation:
2,654$
Step-by-step explanation:
8a + 2c
8 x 238 = 1,904
2 x 375 = 750
750 + 1,904 = 2,654
2,654$
