Can I receive a BRAINLIEST please
We'll use the Pythagorean Theorem (otherwise known as the Distance Formula):
Going from Q to P, x increases by 1 and y increases by 7. Thus, the component form of QP is <1,7>, and the magnitude of this vector is √(1^2+7^2) = 5√2.
Note: this is equivalent to <1, 7>, square root of 50.
Answer:
MN=23
Step-by-step explanation:
For the midsegment:
MN=(WZ+XY)/2
10x+3=(11+8x+19)/2
10x+3=4x+15
6x=12
x=2
MN=10×2+3=23
