Now you've got me stumped. I don't understand why it would be option B :/

So the area of a triangle is the following: A =( B x H) / 2 Let's plug in what we've been told in the question 24 = (3B x B) / 2 48 = 3B x B 48 = 3B^2 16 = B^2 + or - 4 = B I would go with option C because if you plug in 4 in or -4 for B into the area of a triangle equ...

You've got me stumped on this one too. I hope you understand why it's option B because I have no idea.

I would also go with C because: (-12x)(-12x) = 144x^2 (12x)(12x) = 144x^2

Chance of not getting heads: 1) Toss # 1: 1/2 2) Toss # 2: 1/2 3) Toss # 3: 1/2 1/2 * 1/2 * 1/2 = 1/8 So I think the probability would be 1/8.

Formula for area of a triangle is: A = (B x H) / 2 A = (14 x 5.5) / 2 A = ? cm^2 Plug it into a calculator and do the math.

15x^2 + 100x + 125 First I would factor out a 5 because I know 5 can go into 15, 100 and 125. 5 (3x^2 + 20x + 25) Now I would factor what is in the brackets. I used the quadratic equation and got the following solutions for x: x= -5 or x= -5/3 Therefore, the final factored for...

Times refer to multiplication so whats is 45 multiplied by 2? Can you answer that?

So Jay ate 2/15 of 5/8. 'Of' in math refers to multiplication so i think you would simply do the following: 2/15 * 5/8 = 10/120 = 1/12 I'm not 100% sure if I did this correctly. I think someone should verify this.

2x = 368 - 4 2x = 364 2x/2 = 364/2 x = 182
