Answer:
82°
Step-by-step explanation:
total wine of quadrilateral=360°
130+ 46+ 102 +x =360
x=360- 278
x=82°

Answer:
16.65
Step-by-step explanation:
37 * 0.45 = 16.65
Answer:
See below.
Step-by-step explanation:
The question doesn't ask you to find the area, it just ask for the expression that represents the area.
The area of rectangle is A=bh, where b and h are each of the side lengths.
Since we know the sides are (2x+7) and (5x+9), this means that the expression for the area of the rectangle is:

To find the degree and classification, expand the factors:

Thus, this is a second degree quadratic expression
And from Part A, when we multiplied (2x+7)(5x+9), we got another polynomial (10x^2+52x+63). Thus, this rerepresents the closure property of polynomials, where multiplying a polynomial by another gets another polynomial.
