Answer:
B. x=3/7 y=22/7
C. because it is not precise
D. you need to replace these values in the above equation
<u>Check Understanding</u>
to find the intersection point:
y=y
-3x-2=x-10
solve, x=2
B. by graphing the 2 lines (equations)
Step-by-step explanation:
5a+3b
5(2)+3(4)
10+12
22
(5+a)(3+b)
(5+2)(3+4)
(7)(7)
49
The order of the steps differ for the two expressions because for the first expression, you multiply 5a and 3b first. Then, you add them together. However, for the second expression, you add what's inside the parenthesis first then multiply them. So, the order of the steps is the opposite of the other expression.
Step-by-step explanation:

- Length of MN ( Base ) = 8
- Length of NL ( Hypotenuse ) = 10

- Length of LM ( Perpendicular )

Answer: B
Explanation: an isosceles triangle has 2 sides that are the same, so if the base angles are both 34° then you can multiply that by 2 to get 68°. After that you know that you're still missing one of the angles so that missing angle is x. The equation you can set up to solve for x is the following: 68° + x° = 180°
Hope this helped! :)
