Hey there! :)

Answer:

x = 242 mm.

Step-by-step explanation:

Begin by setting up a proportion between the actual college building and the drawing.

\frac{22mm}{9m} = \frac{x}{99m}

Cross multiply:

99 × 22 = 9 × x

2178 = 9x

Divide both sides by 9:

2178/9 = 9x/9

x = 242 mm.

Angle 1 and angle 3 are complementary and angle 1 =~ angle 2 which one of these statements will always be true
n200080 [17]
Can you add the options?
Also since the options aren't there I'll just help set up.
So angle 1 and angle 3 add up to 90 degrees. Angle 1 and Angle 2 are equal so whatever option has something around those lines is correct.

Answer:

A. The coefficients of the sum are whole numbers and the sum is a polynomial.

Step-by-step explanation:

The approach to demonstrate the closure property for the sum consists in defining what a polynomial is and demonstrate that the sum of two polynomials with integer coefficients is equal to a polynomial with integer coefficients. We proceed to show the proof below:

1) 5\cdot m -3, 2\cdot m + 4 Given

2) (5\cdot m -3)+(2\cdot m +4) Definition of addition

3) (5\cdot m +2\cdot m ) +[(-3)+4] Definition of substraction/Associative and Commutative properties

4) (5+2)\cdot m +1 Distributive property/Definition of substraction

5) 7\cdot m +1 Definition of addition/Result

Hence, the coefficients of the sum are whole numbers and the sum is a polynomial. The correct answer is A.
