Answer:
=5a+7b
Step-by-step explanation:
Expand: 5(a + 2b): 5a + 10b
=5a+10b-3b
<em>Add similar elements: 10b-3b=7b
</em>=5a +7b
Answers:
B. <span>The x-coordinate of point A is 5.
</span>E. <span>Point A is on the x-axis.
</span>
Explanation:
Any point drawn on the coordinates has the general notation of (x,y).
The given point is (5,0). This means that:
The x-coordinate of the point is 5
The y-coordinate of the point is 0
Now, let's check the place of this point.
The x-coordinate of the point is 5. This means that we will move 5 points to the right of the origin on the x-axis
The y-coordinate of the point is 0. This means that we will not move along the y-axis which means that the point stays on the x-axis.
Now, comparing the deduced results with the given choices, we will find that the correct choices are B and E
Hope this helps :)
As there is no x axis it will have to be vertical as the y axis is already vertical
Answer:
A, 1,2
Step-by-step explanation:
we translate it first into language of math
we use n for the number
n² = 3n - 2
then, do some algebra things
n² - 3n + 2 = 0
then factorize it
(n - 2)(n - 1) = 0
first n
n - 2 = 0
n = 2
2nd n
n - 1 = 0
n = 1
so n can be 1 or 2
