Step-by-step explanation:
step 1. The square matrices are C and D.
step 2. If you add up the top rows you get 2, 8, -4 .
step 3. The answer is B.
Answer:
u^2 + 9
Step-by-step explanation:
you would have to put the exponent on the u and 3
so it would by u^2 + 3^2
but simplified it would be
u^2 + 9
we cannot simplify further since we don't know what u equals
Answer:
B
Step-by-step explanation:
9514 1404 393
Answer:
x = -3/2
Step-by-step explanation:
The zeros of the function are the values of x that make the factors zero:
x = -4, x = 1
The axis of symmetry is the vertical line halfway between these zeros.
x = (-4 +1)/2 = -3/2
The equation of the axis of symmetry is x = -3/2.
Answer:
Area: x^2+x-6
Perimeter: 4x+2
Step-by-step explanation:
Area: multiply x+3 and x-2 and combine the like terms
Perimeter: multiply the length and width by two, then combine the like terms.
