Answer:
The length of the longest side is 68mm
Step-by-step explanation:
The perimeter of a triangle is equals to the sum of all its sides
P=a+b+c
The triangle is isosceles, so two of its sides are equal, have the same length.
So: a=b, then
P=2a+c=168mm
Moreover, we know that the base is 18mm more than each of the legs, this means: c=18mm+a, where we obtain that a=c-18mm.
So, the system of equations is solved, lets use the above result in Perimeter`s equation.
168mm=2*(c-18mm)+C
From here we have:
168mm=3c-36mm
We obtain the following result: c= 68mm, this the length of the longest side
Answer: I think it is if I'm understanding correctly
True
Step-by-step explanation:
((p ∧ q) → r)
(p → (q → r))
from (if p and q are true then r is true) we can prove (if q is true
then r is true, if p is true)
Answer:
m = (8+3n)/4
k = 55j+20
Step-by-step explanation:
4m -3n = 8
Add 3n to each side
4m-3n+3n = 8+3n
4m = 8+3n
Divide by 4
4m/4 = (8+3n)/4
m = (8+3n)/4
(k-20)/5 = 11j
Multiply each side by 5
(k-20)/5 *5= 11j*5
k-20 = 55j
Add 20 to each side
k-20+20 = 55j+20
k = 55j+20
