<h3>
Answer: B) 39</h3>
==========================================================
Explanation:
Equilateral triangles have three equal sides, ie the sides are all the same length.
Let's set sides ST and TU equal to each other and solve for x
7x-10 = 2x+25
7x-2x = 25+10
5x = 35
x = 35/5
x = 7
Then we use this to compute each side
- ST = 7x-10 = 7*7-10 = 49-10 = 39
- TU = 2x+25 = 2*7+25 = 14+25 = 39
- US = x^2 - 10 = 7^2 - 10 = 49-10 = 39
Each side is 39 units long, so this confirms we have the correct answer.
Answer:
cool
Step-by-step explanation:
like the picture good job
4/x³ - (2x-1)/3x
= (4*3) - (2x-1)(x²) / 3x³
= (12 - 2x³ - x²) / 3x³
= -2x³ -x² + 12 / 3x³
The answer is C.
Hope it helps!
Answer:
<CDG and <CDB are supplementary angles.
Step-by-step explanation:
Equation for circle centered at origin:
x² + y² = r².
Therefore r² = (-4)² + (-2)² = 20, r = √20.
Hence d = 2r = 2√20 = 8.94 (2d.p.)
