x2 - 14x + 49 = (x - 7)2
Length plus height plus width.
10,000 square feet = 1,111.1 square yards.
U turn a square into four squares by making a plus sign
The surface area is length times width plus length. Then you find the square root of the width divided by two and then squared. You add this to the height squared plus the width. The width is multiplied by the square root of 1/2 squared plus the height squared.
The given quadratic expression can not be factored as a perfect square.
false!
Yes.
True
Factors are (7y - 3)(7y - 2) so it's not a perfect square.
64
Yes. (Y+5)2
Yes; the factored form would be (9c+4)(9c+4) or just (9c+4)2 Since the two factors are the same, the beginning trinomial 81c2+72c+16 is a perfect square trinomial
(x + 3)(x + 3)
81.
yes, (7x - 4)2
Yes (x+3(x+3)
