Answer:
91
Step-by-step explanation:
you add the numbers that are in the () then you times those two numbers together and you will get the answer
Answer:
Unlike
Step-by-step explanation:
When it comes to like terms, the numbers must have the same ending variable, 2xy and 2xyz do not have the same ending variable, which seeing it, one ends with 2xy and the other with 2xyz. Therefore these terms are not the same and the answer is unlike.
The portion of the parabola can be parameterized by
where
.
Now the line integral can be computed as
Answer:
Option A is correct.
The length of AC = 136 unit.
Explanation:
AA(Angle-Angle) similarity postulate states that two triangles are similar if they have two corresponding angles that are congruent or equal in measure.
First show that ΔBAC and ΔDEC are similar triangle.
In ΔBAC and ΔDEC
[Angle] [Given in figure]
[Angle] [Given]
then, by AA postulates we can say that ;
In similar triangle, their corresponding sides are in proportion.
Therefore, in ΔBAC and ΔDEC
......[1]
from the figure, we have
AB = 51 unit , AC = 144-x unit , DE =3 unit and CE =x unit.
Substitute these in [1] to solve for x;
Simplify:
By cross multiply we get;
or
or
18x =144
Divide both sides by 18 we get;
x = 8.
Then, the length of AC = 144-x =144-8 = 136 unit.
