Answer:
12 units^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh
A = 1/2 ( 6 ) * 4
A = 1/2 (24)
= 12 units^2
(3x−2)(2x^2+5)
=(3x+−2)(2x^2+5)
=(3x)(2x^2)+(3x)(5)+(−2)(2x^2)+(−2)(5)
=6x^3+15x−4x^2−10
=6x^3−4x^2+15x−10
The formula can also be proved using a trigonometric substitution . Each of above proofs will generalize to show that the volume of an ellipsoid with semi-axes A, B and C is just
(4/3)*Pi*A*B*C
1. Yes it shows proportional relationship because they go by 5.
2. okay.. so your answer choices are 3) 2, 4) 10, 5) -2, and 6) 8. I'M GONNA GUESS. it's going to be #3.
3. Okay so $100- 30 - 10 = $60 That means that each hat cost $6 dollars and he bought 10 of them so 10 times 6 equals 60.
4. they cost 4.50 because she bought ten of them so if you multiply 4.50 by ten you get 45 and she had 5 left over.
Hope this helped!
:)
Please tell me which ones were wrong and which ones were right!
8. 12d-5
10. 25h+100
I hope that helps
