Answer:
answer maybe x^2 + 3x - 28
explanation
first of all this is how any number of such a kind shud be written
ax^2 + bx + c
so that rearrange it
7x^2 + 3x -4
but I personally would go further to put it like this
x^2 + 3x - 28
both answers are the same so but maybe one is more considered since ur qn requires standard form
in case of any misunderstanding plizzz reach out for further explanation
hope this helps
Answer:
A = 63.59
C = 28.26
Step-by-step explanation:
r = 4.5
Area of a circle:
A = πr²
A = 3.14(4.5²)
A = 3.14(20.25)
A = 63.59
Circumference:
C = 2πr
C = 2(3.14)(4.5)
C = 28.26
Answer:
c
Step-by-step explanation:
the equation would be C because
A would end up with a negative amount
B is more than she originally has to paint and
D has the wrong coefficient for <em> t</em>.
Hey!
So the first thing we can notice is that we are given the equation of the line parallel to the one we need to find. Two parallel lines always have the same slope. We can tell by looking at the equation that the slope of the line that we have been given is 1 and since the lines are parallel the slope of the line we need to find is also 1.
Knowing this and a point that the line passes through, we can find the y-intercept or b:
y = mx + b
4 = 1(1) + b
4 = 1 + b
3 = b
Since we know that the y-intercept is 3, we can plug this back into the slope intercept form equation along with the slope to get our equation:
y = x + 3
