Answer: 75 square

Explanation:

Width is X

Length is 3x

Every rectangle has 2 equal widths x 2 equal lengths

Perimeter is 2x + 2(3x) = 40

X = 5

Width is now 5in

Length is now 15in

Area is 75in^2

Half of a perimeter is length + width, which equals to 20in

4x = 20, CX = 5

= 75 sq

**Answer:**

56

**Step-by-step explanation:**

a + 89 + b

Let a= 12 and b = -45

12 + 89 - 45

101-45

56

The <em><u>**correct answer**</u></em> is:

SAS

**Explanation**:

In the diagram, we have that CE and ED are congruent.

We also know that ∠FEC≅∠FED; this is because these two angles form a linear pair. A linear pair has a sum of 180°; since m∠FED = 90°, this means that m∠FEC = 180-90 = 90°, and the two angles are congruent.

We also know that FE = FE, due to the reflexive property.

This gives us two sides and the angle between them, or SAS.

**Answer:**

**The asnwer is 3x + 12y + 4**

**Answer:**

**<em>8 - 5 = m(5 - 0)</em>**
