Answer:
-7 .5+ 2.5 i
Step-by-step explanation:
(-11+i) (-4+ 4i)
find the midpoint
use the same formula for midpoint we use for x and y
midpoint = (a1+a2)/2 +(b1+b2)/2 i
midpoint =( -11+-4)/2 + (1+4)/2 *i
= -15/2 + 5/2 i
-7 .5+ 2.5 i
Answer:
120
Step-by-step explanation:
angle AC = 180, so 3x = 180, so x = 60. Accoding to the Adajacent Angle Theorem, 2x = AB, so AB = 120.
Unfortunately, you have not shared any illustration of this picture-in-a-frame, and thus I don't know the dimensions of the picture.
But suppose that the dimensions are 8 by 10 inches.
Then the total area of the picture-with-2"-frame is (8+2)(10+2) square inches = 10(12) square inches = 120 square inches.
Answer:
it's 91
Step-by-step explanation:
it's easy if the total perimeter is 306 then there is two height and two width so it says the width is 62 then do 62+62 or 62*2 which is 124 then 306-124 which is 182 then divide that by two because there is two length
