Answer:
2x+5
Step-by-step explanation:
Formula for the perimeter of a reactangle= 2(l+b)
So,
2(l+b) = 10x+18
2(3x+4 + b) = 10x+18
Rearrange and solve
3x+4+b = 5x+9
b = 5x+9 - 3x - 4
b = 2x+5
Thus the measurement of the width = 2x+5
Hope this helps
Answer:
2
Step-by-step explanation:
Identify the coordinates as x1, y1 and x1, y2. Solve by using the formula of slope(gradient)
If that little dot after the '1' is a comma, then you're correct. Melting doesn't change the mass.
Answer:
C
Step-by-step explanation:
(f + g)(x) = f(x) + g(x) , thus
f(x) + g(x)
= 2x + 1 + x² - 7 ← collect like terms
= x² + 2x - 6 → C
