Answer:
D
Step-by-step explanation:
x(-3x+4)=x*(-3)+x*4=-3x^2+4x
D) -3x^2 +4x
When multiplying two variables you have to add the exponents together. Techincally x has an exponent of 1 so does -3x. 1+1 = 2 so the first term is -3x^2 and the next one is 4x
a)4.67
b) 2.27
do you not have a calculator? :/
Yes , taking root on both sides we have y = √(4-x^2) so y is dependant on x and x only..so y is a function of x .
