\(\lim _{x\rightarrow 2}\left(bx^{2}+5x-4\right)=-2\)
A necklace is made using blue and silver beads in the ratio 3 : 2. If there are 80 beads in the necklace:
How many are blue?
15<4n<28
4r^3 = 10^2*30
T = kr^(−5/p)
step by step to solve 4r^3 = 10^2*30
$$\frac{34(3x+9)}{12}$$
y = x2
– 2x -3 ,
$$(3x+9)+\frac{4(3x+9)}{3}+\frac{2(3x+9)}{4}$$
12÷2+3×4
