1 mt= 39.37 inches, 5 meter= 5*39.37=196.85 inches. If Michelle walked 5 meters, she walked 196.85 inches.
f(x) = x^4 + 64x^2
Answer:
The answer to this problem is True.
Answer:
10x^2 + 3x - 2
Step-by-step explanation:
To find the sum of the polynomials, add the like terms together. The sum of the given polynomials is 10x^2 + 3x - 2.
To find the sum of the polynomials, you need to add the like terms together. Start by adding the coefficients of the x-squared terms, which are 8 and 2. This gives you 10x^2. Then, add the coefficients of the x-terms, which are -7 and 10. This gives you 3x. Finally, add the constant terms, which are 3 and -5. This gives you -2. So, the sum of the polynomials is 10x^2 + 3x - 2.

Answer:
U (1, 16 )
Step-by-step explanation:
given endpoints (x₁, y₁ ) and (x₂, y₂ ), then the midpoint M is
M = ( , ) ← midpoint formula
let (x₁, x₂ ) = U (x, y ) and (x₂, y₂ ) = V (13, 8 )
substitute these values into the midpoint formula and equate to the corresponding coordinates of M (7, 12 )
= 7 ( multiply both sides by 2 )
x + 13 = 2 × 7 = 14 ( subtract 13 from both sides )
x = 1
and
= 12 ( multiply both sides by 2 )
y + 8 = 2 × 12 = 24 ( subtract 8 from both sides )
y = 16
coordinates of U = (1, 16 )
