Answer:
Step-by-step explanation:
47 . x = 32
x= 32/47
Option 1 : -22
using formula
(a + b )(a - b ) = a^2 - b^2
(√10 + 2√8) (√10 - 2√8)
= (√10)^2 - (2√8)^2
= 10 - 2×2×8=10-32
= -22
2nd question answer is option 3
Answer:
Instead of moving right 4 times and up 7 times, John moved left 4 times and down 7 times.
Step-by-step explanation:
(x + 4, y + 7) = Right 4, Up 7
NOT
(x - 4, y - 7) = Left 4, Down 7
Answer: statement 2: a square is always a rhombus.
Step-by-step explanation:
A parallelogram does not have all the interior angle as right angle.
Therefore, it does not satisfy property of rectangle.
A square has all sides equal and its diagonals are perpendicular bisector.
Thus, square satisfies all the properties of rhombus .
A rectangle does not have all the sides are equal.
Therefore, it cannot b e a square.
