Here, hopefully this picture cane help
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:
the slope is zero because anything times 0 is zero
Step-by-step explanation:
Answer: D x>_ 0
Step-by-step explanation: Because the circle is shaded and the x can only get bigger (ex: Can’t be -1 or -3)
Answer:
x = 116° , y = 20°
Step-by-step explanation:
Since, measure of angle subtended on the center of the circle is twice the measure of angle subtended on the circumference of the circle.
Now, by angle sum property of a quadrilateral.
