Answer:
RC = 40
Step-by-step explanation:
Note that the circumcentre is equally distant from the triangle's 3 vertices.
That is : PC = RC = QC
Equate any pair and solve for x
Using RC = PC, then
5x - 15 = 3x + 7 ( subtract 3x from both sides )
2x - 15 = 7 ( add 15 to both sides )
2x = 22 ( divide both sides by 2 )
x = 11
Hence
RC = (5 × 11) - 15 = 55 - 15 = 40 units
The slope is:(9-3)/(1-(-2))=6/3=2
Answer:
put a picture up
Step-by-step explanation:
Answer:
I resolve the expression
(4x+3) (3x-8)=12x2-32x+9x-24
12x2-23x-24
the polynomial (4x+3) (3x-8) is equivalent a the expression 12x2-23x-24
Answer:
v = 220 yd²
Step-by-step explanation:
Small portion
v = 5 * 4 * 3
v = 60 yd²
Large portion
v = 9 * 6 * 3
v = 162 yd²
Total
v = 60 + 162
v = 220 yd²
