Answer:
Step-by-step explanation:
This will be solved using distance formula between two coordinates.
The distance formula between two coordinates is given as;
d =
Point T has coordinate of T(80,20)
Distance to Point U(20,60) is;
TU =
TU =
TU ≈ 72 Units
Distance From Point U(20,60) to Point V(110,85);
UV =
UV =
UV ≈ 93 units
I didn't bother to calculate TV because we are looking for shortest distance for the trip and by inspection if he goes from T to V first before Point U, it will be a longer journey.
Thus, shortest distance = TU + UV
shortest distance = 72 + 93 = 165 units

It has 2 equal sides
Answer:
Andrew has 9 cars
Step-by-step explanation:
Let's start by defining what our unknowns are and how to name them:
For the number of cars Andrew has: let's use the letter A
For the number of cars Luke has: let's use the letter L
Not write the first sentence in mathematical terms:
"Luke has 4 more than triples the number of cars that Andrew has."
L = 3 * A + 4
The second phrase results on a very simple equation since it just states the number of cars that Luke has:
L = 31
Now we can combine these two equations by replacing the variable "L" in the first equation with the second equation and then solve for A:
L = 3 * A + 4
31 = 3 * A +4
31 - 4 = 3 * A
27 = 3 * A
A = 27/3
A = 9
Therefore, Andrew has 9 cars.
Answer:
D
Step-by-step explanation:
when you plug in 16 for x you will get -621.
To represent this statement I put it in an expression thingy -3 ⩽ p <1
