Ulterior exterior angles:

50+2y =180

50+x+5=180 55+x=180

50-50+2y=180-50

2y/2=130/2

y=65

use the ruler provided to measure the base of the parallelogram shown to the nearest 0.5 CM which measurement is the closest to

valkas [14]

Answer:

Area of the parallelogram = 21.6 cm²

Step-by-step explanation:

Area of a parallelogram = Base × Height of the side parallel to the base

By using ruler,

Base = 4.8 cm

Height of parallelogram = 4.5 cm

Area of the parallelogram = 4.8 × 4.5

= 21.6 cm²

Quadrilateral ABCD is a a square and the length of BE is 6 cm.<br><br>What is the length of AC?

Aloiza [94]

The answer is: 12 centimeters.

The explanation is shown below:

1. By definition, all four sides of the square are equal and the diagonals are equal too.

2. Keeping the information above on mind, you know that AC and BD are equal:

$AC=BD$

3. Then, the length of BD is twice BE. So, you can calculate it as following:

$BD=2BE$

$BD=2(6cm)\\BD=12cm$

4. Therefore, the lenght of AC is:

$AC=12cm$

Which expression has a value that is equivalent to the given expression when n = 8?

mrs_skeptik [129]

Q1.

Put the value of n = 8 to the expressions:

2n + 10 → 2(8) + 10 = 16 + 10 = 26

A: 3n → 3(8) = 24 ≠ 26

B: 2(n + 5) → 2(8 + 5) = 2(13) = 26 :)

C: n² + 5 → 8² + 5 = 64 + 5 = 69 ≠ 26

D: 10n + 2 → 10(8) + 2 = 80 + 2 = 82 ≠ 26

<h3>Answer: B: 2(n + 5)</h3>

Q2.

x = 3, y = 2

L = 5y² - 2x → L = 5(2)² - 2(3) = 5(4) - 6 = 20 - 6 = 14

R = x² + ... → R = 3² + ... = 9 + ...

A: x² + x → 9 + 3 = 12 NOT

B: x² + y → 9 + 2 = 11 NOT

C: xy → 9 + (3)(2) = 9 + 6 = 15 YES

D: 2y → 9 + (2)(2) = 9 + 4 = 13 NOT

5y² - 2x < x² + xy

L = 14, R = 15, L < R CORRECT

<h3>Answer: C: xy</h3>

Q3.

3 + 6² = 3 + 36 = 39

A: 3³ + 12 = 27 + 12 = 39 NOT

B: 5² + 4² = 25 + 16 = 41 > 39 YES

C: 2³ + 5² + 6 = 8 + 25 + 6 = 39 NOT

D: 2³ + 14 + 17 = 8 + 14 + 17 = 39 NOT

<h3>Answer: B: 3 + 6² < 5² + 4²</h3>

Use the FOIL method to evaluate the expression

In-s [12.5K]

So u multiply each term in the first parentheses by each term in the second parentheses.

√5 √5 + 6√5-3√5 - 3x6
Now you multiply the numbers which will get u:
5+6√5 - 3√5 - 18
Then subtract:
-13 +3√5 that’s your answer
