Answer:
expression: 3(d+35)
simplified expression: 3d + 105
Step-by-step explanation:
The first drone costs d. This means the expression = d
The second drone costs d and an additional $35. Expression = d + 35
The third drone costs 3 times as much as the previous one. Expression = 3(d+35)
To simplify it, you just distribute. Hope this helps :)
Answer:
6 x 10 = 60, 60 divided by 2 ( x 1/2 ) = 30
Step-by-step explanation:
Formula area of a triangle:
B(base)H(height) x 1/2
In this case 10 is your base and 6 is your height.
Answer: intersecting but not perpendicular
Step-by-step explanation: Let's start by eliminating a few options.
First off, parallel lines are coplanar lines that do not intersect.
In the diagram shown, lines <em>i </em>and <em>k</em> do intersect
so option A doesn't make any sense.
We can also eliminate option C because by definition,
parallel lines <em><u>do not intersect </u></em> so we can cross this off.
We also can't conclude that lines <em>i</em> and <em>k </em>are perpendicular,
because we don't have a box at the vertex and from the
diagram shown, it doesn't look like they form a perfect right angle.
That leaves us with option D.
Notice that these two lines cross at a point.
When two lines cross at a point, we say that they intersect.
So they are intersecting lines but not perpendicular.
Mm I don't know, why is that question? You must have an weird teacher
Your goal here is to determine the value of x.
Use the principle of similar triangles:
x is to 12 as 6 is to 8:
x 6
--- = ----
12 8
Therefore, 8x = 72, and x = 9 (answer)
