To answer the problems correctly, you have to follow and pay close attention to whether or not it says "Area" or "Perimeter". For example, for the first problem, area of 63 square units, you would have to create a shape thats sides multiply out to equal 63 units squared. He could draw a square with 9 units by 7 units. This would work because 9x7=63. For perimeter, all four sides must add up to equal 38 units. Feel free to get creative with the shape on this one! If you have any other questions, just ask. Hope I helped some. :)

Which equation is in point-slope form for the given point and slope?
Neko [114]
First,we need to understand the point-slope form:
y1 - y2 = m(x1 - x2)
Where x and y are the coordinates and m is the slope.

Put the above information into the equation:

y-(-6)=-3/4(x-2)
y+6 = -3/4 (x-2)

Therefore the answer is C.y+6 = -3/4 (x-2).

Hope it helps!

Show that one zero of 8x230x27 is the square of the other.
murzikaleks [220]

Answer:

8x2-30x+27 has one root (9/4) the square of the other (3/2)

Step-by-step explanation:

8x2+30x+27 = (2*x+3)*(4*x+9)  => solution = {-3/2, -4/9}

One is not the square of the other because squares are positive.

8x2-30x+27 = (2*x-3)*(4*x-9)  =>

solution = {3/2, 4/9}   since (4/9 = (3/2)^2, therefore the preceding question is correct.
