1 3/4 - a fraction less than 3/4 (i think ><)
Answer:b
Step-by-step explanation:
f(x)=x^3+2x^2-5x-6
Put x= -3 in the equation
f(-3)=-3^3+2*3^2-5*3-6
= -27+18+15-6= 0
f(2)= 2^3+2*2^2-5*2-6
=8+8-10-6= 0
Answer:
Tan is the ratio of "opposite" side to "adjacent side
Cos is the ratio of "adjacent" to "hypotenuse"
Sin is the ratio of "opposite" to "hypotenuse"
We will write the trig ratios with respect to the angle "x"
Opposite Side is "c"
Adjacent Side is "b"
Hypotenuse is the side opposite of 90 degree angle, "a"
Now, let's write the ratios:
Step-by-step explanation:
5(x+1)-2x=2(3+x) —> factorise
5x+5-2x=6+2x —> - 3x
3x+5=6+2x —> -2x
x+5=6 —> -5
x=1
