Answer:
15i and 4i
Step-by-step explanation:
i is an imaginary number also shown as
.
Since we have 
, thats 15* . Substitute for i and we get 15*i or 15i.
We do the same for 
. This is 4* or 4*i or 4i.
An easy way to do this is to take the negative inside the square root like 
, take the absolute value -6 absolute value=6 and times it by i. So now it becomes 6i
Answer:
i thought it was just the area i dont know how to do literal area yet sorry
Step-by-step explanation:
Answer:
D) the value of x is 135, because the angles shown in each diagram are complementary
Step-by-step explanation:
Each diagram has 2 angles labeled, and those two angles are always supplementary. The sum of the measures of two supplementary angles is 180°.
x + 45 = 180
x = 180 - 45
x = 135
Answer: D) the value of x is 135, because the angles shown in each diagram are complementary
Answer:
390 
Step-by-step explanation:
We know that the top is a rectangle triangle, we only have two of the tree sides and the one that is missing is the hypotenuse. The formula to find it is 
If we put the values we know it would be
= 13
So now we have the lenght missing.
The area of the top and bottom is the same and we found it by the formula 
= 
= 30, that is the area of just one triangle, multiply by 2 and that is the area of top and bottom = 30 x 2 = 60
The area of a rectangle is base x height, we have three rectangles.
First one: 13 x 11 = 143
Second one: 5 x 11 = 55
Third one: 12 x 11 = 132
The sum of the areas would be = 60 + 143 + 55 + 132 = 390
<span>2(3 - x) = -16
3 - x = -16/2
3 - x = -8
-x = -8 - 3
-x = - 11
x = 11</span>
