Rewrite 4x^2-3x+9=2x+1 as 4x^2-5x+8 = 0
Here, a = 4, b = -5 and c = 8. Then,
5 plus or minus sqrt (25 -4(4)(8) )
x = ------------------------------------------------------
8
5 plus or minus sqrt (-103)
= --------------------------------------
8
5 plus or minus i*sqrt(103)
Then x = ----------------------------------------
8
= ---------------------------------------------
8
= ----------------------------
Answer:
C
Step-by-step explanation:
Answer:
7/2
Step-by-step explanation:
The slope of the line is given by
m = (y2-y1)/(x2-x1)
= (12-5)/(3-1)
= 7/2
Answer:
Step-by-step explanation:
The area of the given squares are
Area = 64 in
Area = 225 in
Area = 289 in
The length of each side of a square is determined by finding the square root of its area. For the first square, the length of its side is √64 = 8inches. For the second square, the length of its side is √225 = 15inches. For the third square, the length of its side is √289 = 17inches.
For a right angle triangle to be formed, Pythagorean theorem must be obeyed. Sum of the square of the smaller sides must equal the square of the longer side. Therefore,
8² + 15² = 17²
289 = 289
Therefore, the correct statement is
Yes, a right triangle can be formed because the sum of the areas of the two smaller squares equals the area of the largest square
