Answer:
8/5-12x.
Step-by-step explanation:
To distribute, you simply need to multiply each of the terms inside of the parenthesis by -4. This will give you:
=-4()-4(3x)
=8/5-12x. This is your answer!
The surface area of a triangular prism with the 3 sides slant height as 14 the base width as 8 and the base height as 6.9 is 155. 705 in²
<h3>
What is the surface area of a triangular prism?</h3>
The surface area of a triangular pyramid is the total area of all it's faces.
The properties of a triangular prism are;
- It is bounded y three lateral triangular faces meeting at one vertex.
- It has all its faces as triangles
<h3>
How to determine the surface area</h3>
Surface area = Base Area + 1÷2 (perimeter × base height)
But base area = 1÷2 (base side × height)
Base area = 1÷ 2 (8 × 14) = 0.5 × 112 = 56 in²
Perimeter = sum of all the sides = 14 + 8 + 6.9 = 28. 9 in
Base height = 6. 9in
Surface area = 56 + 1 ÷ 2 ( 28.9× 6. 9) = 56 + 0.5 × 199.41 = 56 + 99. 705 = 155. 705 in²
Surface area = 155. 705 in²
Therefore, the surface area of the triangular prism is 155. 705 in²

Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.
Answer:
6.99x 10^(7) = 69,900,000
3.61x10^(7) = 36,100,000
8.3x10^(6) = 8,300,000
question 1
114,300,00 is them all added up
1.143x10^(9) is standard form
and i do belive part a's answer is the 6.99x10^(7) and so on and so forth. I hope this helps. X3 i did my best.

Answer:
31.5 ft
Step-by-step explanation:
Use the Pythagorean Theorem
a² + b² = c²
Plug in the knowns
a² + 23² = 39²
Subtract 23² from both sides
a² = 39² - 23²
a² = 1521 - 529
a² = 992
Take the square root of both sides
a = 31.496031496
Rounded
a = 31.5 ft
