Answer:
b=2
Step-by-step explanation:
-12+3b-1=-5-b
Combine like terms
-13 +3b = -5-b
Add b to each side
-13+3b+b = -5-b+b
-13+4b = -5
Add 13 to each side
-13+13 +4b = -5+13
4b = 8
Divide by 4
4b/4 = 8/4
b = 2
in 1st figure
2:1=(x+2):2
2/1=(x+2)/2
4=x+2
x=2.
Similarly in the 2nd figure
8:5=(8+3):(5+x)
8/5 = 11/ (5+x)
8(5+x) =55
40+8x=55
8x=15
x=15/8
x=1.875
Answer: 46-3i
Step-by-step explanation: Use the FOIL method, (a+b)(c+d)=ac+ad+bc+bd. Collect like terms then simplify.
(6+7i)(3−4i)
18−24i+21i+28
(18+28)+(−24i+21i)
46-3i

Answer:
<h2>brainiest me</h2>
Step-by-step explanation:
a dart thrown at the board is equally likely to land anywhere on the board. What is the probability that the dart lands within the center square? Solution. If the side lengths of the dart board and the side lengths of the center square are all then the side length of the legs of the triangles are . Use Geometric probability by...
There are 8 faces on the figure.
There are two of the same sides so we can multiply that by 2. That side equals 76 in. 76 x 2 =
152.
Then, there is another side that equals 4 x 4 which is
24.
Another side equals 4 x 6 which is
24.
Another one equals 6 x 6 which is
36.
Another side equals 6 x 6 which also equals
36.
Another side equals 10 x 6 which is
60.
The last side is 10 x 6 which equals
60.
Which should add up to 392 in.
