X^2 + 8x + 16 is the answer
Answer:
37
Step-by-step explanation:
45+98+x=180
Answer:
x=52 m1= 40 m2= 140
Step-by-step explanation:
x-12+x+88=180 since they are linear pair
2x+76=180 collect like terms
2x=180-76
2×÷2=104÷2
×=52

You need to solve a system comprised of 3 equations.
1) k+m+n=1500
2) m=3n
3) k=2n
Replace equations 2) and 3) in 1) => 2n+3n+n=1500 => 6n=1500 => n=250
By reaplacing n in 2) => m=3*250=750
In 3) => k=2*250=500
The length of the bacteria should be written in scientific notation.
0.00365 in scientific notation = 3 × 10^-3
Given.
length of the bacteria in decimal = 0.00365 cm long
Scientific notation is written in the format x × 10ⁿ
where,
x = any number between digit 1 and 10
n = exponent (positive or negative).
- To have a negative exponent value, move decimal to the right
- To have a positive exponent value, move the decimal point to the left.
In this case, the nearest significant value is 3
So move the decimal point three times to where 3 is
That is,
0.00365 = 3.65
Since the decimal point is moved to the right 3 times, n = - 3
we have 10^-3
Therefore,
0.00365 in scientific notation = 3 × 10^-3
