C is the correct answer. using the equation (y-y1)=m(x-x1)
Answer:
f(-2) = 4
Step-by-step explanation:
f(x) = x²
f(-2) = (-2)² = (-2)(-2) = 4
Answer:
a) P = 6x + 13//
b) i) x = 5//
ii) 9//
Step-by-step explanation:
a) P = 2(x+2) + 2(2x-1) + 3 + 8 m
= 2x+4 + 4x-2 + 3 + 8
= 6x + 13//
b) i) P = 43 m
43 = 6x + 13
43-13 = 6x
<u>3</u><u>0</u> = <u>6</u><u>x</u><u> </u>
6 6
x = 5//
ii) longest side = (2x-1) m
2 × 5 - 1
10-1 = 9//
