Answer:
state whether this function is quadratic? why or why not?
f(x) = - 3(x - 2)(x + 3)(x + 5)
3(x+6)=-24
Divide both sides by 3
3(x+6)/3=-24/3
X+6=-8
X=-14
Answer:
x = 65
Step-by-step explanation:
if two triangles are similar then we can use the similarity ratio to find the length of CH
60/156 = x/169 cross multiply expressions
156x = 10140 divide both sides by 156
x = 65
Answer:
216
Step-by-step explanation:
A=2(wl+hl+hw)=2·(12·2+6·2+6·12)=216
9.5÷8=1.1875 (distance covered in 0.1 hour)
1.1875 ×10 =11.875
