Answer:
first you need to factorize
the answer is 107
x
−
40
I think the answer should be 10π+ 10m2, because there is 2 semi-circles and one rectangle , and the rule to find area of a rectangle is length x width and the area of a semi-circle is πr2/2, I hope that helps
Answer: 50
Step-by-step explanation:
Substitute 3 for x:
= 20(3)-10
= 50
Answer:
Step-by-step explanation:
It is given that,
The average distance between the Earth and the Moon is 384 400 km.
We need to express in in standard form.
1 km = 1000 m
It means,
384400 km = 384400000 km
or
=
Hence, the average distance between the Earth and the Moon is .
The coefficients in the equation (-x)(3y)(-2x) are the constants -1, 3, and -2.
In order to simplify and determine only one coefficient <span>we should multiply all three constants together to get only one numerical constant .
</span><span>The commutative law</span> says hat you can rearrange a multiplication any way you want. so, (-1)*3*(-2)=(-3)*(-2)=6
The equation can be also simplified written as:
6x^2y
None of the option is the solution.
