Step-by-step explanation:
<u>Step 1: Define Equation</u>
x + 5 = -3
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 5 on both sides: x = -8
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: -8 + 5 = -3
- Add: -3 = -3
Here we see that -3 does indeed equal -3.
∴ x = -8 is the solution to the equation.
Answer: 15x² + 2x + 4
x = -2/3, 0, 1/2
Step-by-step explanation:
5x(3x + 2) - 4(2x - 1)
First, distribute:
15x² + 10x - 8x + 4
Combine like terms:
15x² + 2x + 4
This is your polynomial!
If you needed to solve for x, take your original factored polynomial and set each term equal to 0:
5x(3x + 2) - 4(2x - 1)
5x = 0
x = 0
3x + 2 = 0
3x = -2
x = -2/3
-4 = 0
No solution
2x - 1 = 0
2x = 1
x = 1/2
x = -2/3, 0, 1/2
Hope this helps!
The answer is 40%. Count how many right triangles there are, there are 20 right triangles. Count how many right triangles are shaded in, there are 8 right triangles that are shaded in. 8/20=0.4 or 40%
Answer:
34, 55, 89, 144, 233
Step-by-step explanation:
It adds the numbers up in the order it comes.
So, 1 + 1 = 2
3 + 5 = 8
Stuff like that^^

-- It's exactly 10% shorter than 1 inch, and 92.5% shorter than 1 foot.
-- It's also approximately 0.01343 smoot (rounded).
-- It's also approximately 2.286 centimeters, or 22.86 millimeters,
or 0.0000142 mile.
-- It's also approximately 0.000 000 000 000 000 002 418 light-year.
You see, "9/10 inch" is known and understood precisely wherever inches are
used in the world (everywhere throughout Liberia, Burma, and the USA) exactly
because "inch" is a unit that's exactly defined and agreed on in all those places.
But when you come along and say "I don't know what an inch is, describe it to me
in terms of something else", then you throw people for a loop.
If you can tell us what other unit you want to measure with ... like a flower,
a finger, an animal, or something else that we're also familiar with, then
we'll compare "9/10 inch" to that item for you. But that won't be exact,
because all of those things come in different sizes, and none of them has
a standard size that everybody agrees on.
