Hello there! So, this is a quadrilateral and quadrilaterals equal 360 degrees. Let’s combine like terms to start off. 39x + 9 = 360. First, let’s subtract 9 from both sides to get 39x = 351. Next, divide each side y 39 to isolate the “x”. When you do that, x = 9. Now, let’s plug in the values for each, when you do, here are the final answers.

x = 9
E = 75 degrees
F = 91 degrees
G = 89 degrees
H = 105 degrees

Those are all of the angle measurements, but it wants the measurement of angle H. Therefore, that angle measurement is 105 degrees.

Answer:

a) Shawn's error was that he Multiplied 15 by 2x only. He didn't Multiply 15 by 7

b) The difference, in square feet, between the actual area of Shawn’s garden and the area found using his expression is given as

98 square feet

Step-by-step explanation:

The area in, square feet, of Shawn’s garden is found be calculating 15(2x + 7). Shawn incorrectly says the area can also be found using the expression 30x + 7.

The correct area =

15(2x + 7).

= 30x + 105 square feet

The error in Shawn’s expression is

= 15(2x + 7)

= 30x + 7 square feet

Shawn's error was that he Multiplied 15 by 2x only. He didn't Multiply 15 by 7

The difference, in square feet, between the actual area of Shawn’s garden and the area found using his expression is given as

30x + 105 square feet - 30x + 7 square feet

= 30x + 105 - (30x + 7)

= 30x - 30x + 105 - 7

= 98 square feet

On a road trip, a family drives 350 miles
ExtremeBDS [4]

Answer:

1.14 days (approximately)

Step-by-step explanation:

Family drives 350 miles per day

Let d = days

Equation: 350d = 400

d = 400/350

d is approximately 1.14 days

If you want to answer it without decimals, you should say around 2 days since it's going to take more than one day to travel.

The triangles shown are congruent by the SSS congruence theorem.
denis23 [38]
1. Let's check the problem backwards. So let's map A"B"C" to ABC

2. We first need to reflect  A"B"C" to A"B"C' with A"B"" as the axis of rotation.

3. Then we shift a few units up (translation) A"B"C' to A'B'C

4. Finally we rotate A'B'C around C to map the triangle onto ABC

going backwards we get the answer: b

<span>b.rotation, then translation, then reflection</span>
