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.

i dont understand the question? ?

step-by-step explanation:

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)

answer: b f g .
