Im assuming its x^2+4x+3.....for x squared right.
First get the product of two numbers that equal to 3 (+3 * +1)
But also add up to 4 (+3 + <span>+1</span>)
so you apply them to your x^2
(x+3)(x+1)
Answer:
41.4
Step-by-step explanation: Since this isn't a right triangle and you're given side side side (SSS), you need the Law of Cosines.
cos(c) = (a^2 + b^2 - c^2)/2ab
(100+144-64)/2*12*10
cos(c) = 180/240
multiply both sides of the equation by cos^-1 to get ride of cos:
cos^-1(cos(c)) = cos^-1(180/240)
c = 41.4
Answer:
y=4x-1
Step-by-step explanation:
the lines can be written in their slope intercept form which is y=mx+b
m= slope=4
b=the intercept point=-1
so we have:
y=4x-1
