In 775, the value of 5 is 5. Because it is in the ones place, it is 5.
The value of 5 in 89,507 is 500 because it is in the hundreds place.
Angle 1 = 4x - 16
angle 2 = 2x + 10
4x - 16 + 2x + 10 = 90
combine like terms
6x - 6 = 90
add 6 to both sides
6x = 96
divide both sides by 6
x = 16
angle 1 = 4x - 16 = 4(16) - 16 = 48
angle 2 = 2x + 10 = 2(16) + 10 = 42
Answer:
251.2
I used 3.14 as pi
Step by step explanation:
SA= 2(pi*r²) + (pi*d)h
SA= 2 (
* 4² ) + (pi*8)*6
<u>you could also do this:</u>
SA=2πrh + 2πr²
Answer: y=4,728,779,608,739,020,800
Step-by-step explanation: based on the values you have for m & b it would be...
y=4,200 x 
y=4,200 x 1,125,899,906,842,624
y=4,728,779,608,739,020,800
Answer: a. 30x^2 − 26x − 12
First write the equation in a form to better help visualize.
(5x - 6)(6x + 2)
Then use distributive property on the second binomial from the first binomial. <em>You multiply 5x by 6x and 2, then multiply -6 by 6x and 2.</em>
5x * 6x = 30x^2 (The answer is raised to the power of 2 because you're adding the invisible exponents, aka exponents of 1)
Then multiply 5x by 2
5x * 2 = 10x
Then you repeat the process but with -6 instead of 5x.
-6 * 6x = -36x (It is not raised to a power of 2 because -6 does not have a variable to include the invisible exponent)
-6 * 2 = -12
Now take all of your answers and put them into 1 equation by the order you did them.
30x^2 + 10x - 36x -12
But wait! The answer can still be simplified. All you have to do is combine like terms. <em>However 30x^2 can't be combined with 10x because 10x isn't raised to the second power, terms can only be combined if they have the same variable and exponent.</em>
30x^2 + (10x - 36x) - 12
30x^2 - 26x - 12
