You have to multiply the 2 equations. so it will be 2n^2 ×2n= 4n^2 Then, -7n×2n= -14n Then, -4x2n= -8n Then, 2n^2×-5=-10n^2 Then -7n×-5= 35n Then, -4×-5=20. Combine like terms, 4n^2 -14n -8n -10n^2 +35n +10 = -6n^2+13n+10 After this you can keep it as simplest for OR X-BOX OR FOIL
5 halves left from 0 is -2.5
-3.5 is further left than -2.5 so B
I would go with B i had this question on my test and i got it correct
Answer:
28 inch
Step-by-step explanation:
The length of all four sides of square is equal.
The formula used for finding the area of square is:
Area = (Length) × (Length)
Thus, the Area of square whose length is 2√7 is:
Area = 2√7 × 2√7
⇒ Area = 4 × 7 = 28 inch.
The hypotenuse is 17 feet.
Remember the pythagorean theorem.
For this problem, 8 squared + 15 squared = 289. Then, find the square root of 289, and that is your answer.
