Answer:
aight what's the question
ST is a midsegment, which tells you that BD=2(ST) or ST=½BD. Use that to substitute the values and find ST.
BD=2(ST)
29+x=2(2x+31)
29+x=4x+62
29=3x+62
-33=3x
x=-11
Now that we know x, we can substitute that into 2x+31 to find ST
ST=2x+31
ST=2(-11)+31
ST=-22+31
ST=9
Answer:
12
Step-by-step explanation:
21=31
31=7+2-3+0=12
This is correct because linear equations mean add subtract divide and multiply instead of finding roots and squares
Answer:
20
Step-by-step explanation:
Side of the square = hypotenuse of triangle = √(4² + 2²)=√(16 + 4)=√(20)
Area of a square = (side)² = (√20)² = 20 units²
