Answer: 15in^2
Step-by-step explanation:
first you need to find the area of the rectangle, so you would multiply 7 and 3, which gives you 21, (A=L•W). So now you need to find the area of the triangles, the formula for that is A= 1/2 b•h, so you get 3in for the area of the triangle, but since there are two and they are the exact same triangle you would just combine them, so the area for both triangles is 6in, so then you would need to subtract the 6 from the 21 so that you can find the area of the shape, and your final answer would be 15in(squared). hopefully you understand
Answer:
Y= 1 (x^2-2)-5
Step-by-step explanation:
Use vertex form: y= a(x-h)+<u>k: k is what shifts the parbola up or down. Positive shifts it up while negative shifts it down.</u>

Answer: 20% increase
Step-by-step explanation: It’s out of 100 and you first got 80 and then you got 100. Since it’s out of 100 you could just subtract to numbers ex: 100-80=20. The answer is 20% increase
We just need to solve the equation in order to find the value.

So we subtract 5 from both sides of the euqation and get

Now we divide by 3 on both sides and get

So the answer is C.
Hope this helps!
