Enter your answer in the box.

Do not use decimals in your answer.

Answers

Answer: 14x+74

Step-by-step explanation:

-6x+86-32x-12+52x=14x+74

-6x+86-32x-12+52x

=-6x-32x+52x+86-12

=14x+86-12

=14x+74

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The final expression after simplifying is 14x + 74.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example:

2 + 3x + 4y = 7 is an expression.

3x + 4 = 3 is an expression.

3 + 4x - 5 is an expression.

We have,

-6x + 86 - 32x - 12 + 52x

Add like terms.

-6x - 32x + 52x = 14x

Now,

14x + 86 - 12

14x + 74

Thus,

The final expression after simplifying is 14x + 74.

3. Which number is a natural number?
A-2.5
B 5-151
C-13+51
D|-81-2

Answers

Answer:

C

Step-by-step explanation:

A natural number is a number that you would use to count kids in a class for example. Like, 1,2,3,4 and so on. 2.5 is not a natural number since there cant be 2.5 of a student. 5-151 is a negative number and there cant be negative students. -13+51=38. 38 is a natural number. Now, in D it looks like there mightve been a absolute value sign but im not sure. If D has absolute value signs then D works too. Hope I could help.

12. Carla is lying on the ground between two trees in her backyard. She is 67 feet from the tree to her left. The angle of elevation from her eyes to the top of the tree on the left is 50°. Carla is 75 feet from the tree to her right and the angle of elevation from her eyes to the top of that tree is 36°. a. Determine the height of each tree to the nearest foot. Show your work. b. State which tree is taller, and by how much.

Answers

Answer:

the left tree is taller

Step-by-step explanation:

shown in work above :)

The first tree is taller than the second tree by 25.3 ft.

We have to use the trigonometric ratios and angle of elevation to obtain the height of each tree as follows;

Let the height of the first tree be h1 and the height of the second tree be h2.

For the first tree;

tan 50° = h1/67

h1 = 67 tan 50° = 79.8 ft

For the second tree;

tan 36° = h2/75

h2 = 75tan 36°

h2 = 54.5 ft

The first tree is taller than the second tree by 25.3 ft.

In 1777, Boyrereau Brinch, an enslaved African, joined the Continental Army. In 1783, he was honorably discharged and, because of his military service, freed from slavery. I also entered the banners of freedom. Alas! Poor African Slave, to liberate these freemen, my own tyrants. I went into Capt. [Samuel] Grangers company. We marched to Frog Plain, from there to Second Hill between Reading and Ridgold. General Worcester commanded the British under the command of General Howe, who attacked us. We beat them back; the fight was continued all day, and the victory was sometimes doubtful. Finally, I was in the battles at Cambridge, White Plains, Monmouth, Princeton, Newark, Frogs Point, Horseneck where I had a ball [bullet] pass through my knapsack. All of which are battles the reader can obtain a more perfect account of from history than I can give. At last we returned to West Point and were discharged, as the war was over. Thus was I, a slave for five years fighting for liberty. After we were disbanded, I returned to my old master at Woodbury [Connecticut], with whom I lived one year, my services in the American war having emancipated me from further slavery and from being bartered or sold. Here I enjoyed the pleasures of a freeman; my food was sweet, my labor pleasure: and one bright gleam of life seemed to shine upon me. QUESTIONS:RESPONSES:1.
