Now consider the expression x2 + 6x + 7. The pieces of this
expression can be represented with an "x by x" square, six "x by 1"
rectangles, and seven unit squares.
x2 + 6x + 7
a. Why is it impossible to arrange the given squares and rectangles
without overlapping to form one large square?
b. How could you produce the requested square if you were given
some extra pieces or allowed to take away some pieces? What
addition or subtraction would do the job most efficiently?
c. Explain how your answer to Part b illustrates the fact that
x2 + 6x + 7 = (x + 3)2 – 2.

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
