For the Jet one the answer should be 450 but its not on there
The longest side in the triangle is opposite to the largest angle of this triangle. If triangle is acute, then all angles are acute. Acute angle has cosine that is positive.
Use cosine theorem to determine the cosine of the largest angle:
where
is the largest angle.
Then

Since
then

Divide this inequality by 5:

Note that
then the smallest possible whole-number value of x is 7.
Answer: correct choice is B
Answer:
The point of intersection of the lines is
.
Thus, Ariyonne's claim is incorrect.
Step-by-step explanation:
Given equations:
1) 
2) 
To find the point of intersection, we need to solve the given system of equations.
In order to solve the system we will use substitution method.
We will substitute value of
from first equation in the second equation and solve for 
So, we have

Multiplying both sides by 2 to remove fraction.

Using distribution.

Subtracting both sides by


Adding 4 to both sides.


Dividing both sides by 7.


We can find value of
by plugging in
in the first equation.



So, the point of intersection of the lines is
.
Thus, Ariyonne's claim is incorrect.
Answer:
-8 x 4
Step-by-step explanation:
Multiplication is really just repeated addition. In multiplication, the 2 terms are the number being added and the number of times it is added. In this case, the number being added is -8 and it is being added 4 times. Therefore, the multiplication expression must be -8 x 4.
