Okay first you should look at the denominator and if the denominator are the same you could subtract easily but in this case the denominator are different so you see which denominator is the biggest one and try to chose the small one. So basically what four times what equals to 16 given the 4 and then you multiply the fraction 3/4 by 4 and giving 12/16 and then you subtract and giving the answer 3/16
The correct statements about similarity of triangles are A, B, and C.
<h3>
What is a similar triangle?</h3>
Similar triangles are triangles that have the same shape, but their sizes may vary. This type of triangles are said to have congruent angles and corresponding sides.
From the given figure,
- triangle ABC is a right triangle and triangle BDC is also a right triangle
- triangle ABC is a right triangle and triangle ADB is also a right triangle
- angle ABD is 45 and angle BCD is also 45 degrees.
Thus, the correct statements about similarity of triangles are A, B, and C.

Answer:
(3 + 2x) + (4 – 5x) = 7 - 3x
(3 + 2i) + (4 – 5i) = 7 - 3i
Step-by-step explanation:
In the addition of two binomials you have to add separately each monomial as follows:
(3 + 2x) + (4 – 5x) =
= (3 + 4) + (2x - 5x) =
= 7 - 3x
Analogously, the sum of the complex numbers 3 + 2i and 4 – 5i is made adding the two real parts from one side, and the two imaginary parts from the other side, as follows:
(3 + 2i) + (4 – 5i) =
= (3 + 4) + (2i - 5i) =
= 7 - 3i
Answer:2.625 also 2 5/8
Step-by-step explanation:
Answer:
x = -1/3
Step-by-step explanation:
We have,
sin(x + 7) = cos(4x + 8)
We need to find the value of x.
We know that,
sin(90-x) = cosx
So,
sin(90-(x + 7)) = cos(4x + 8)
cos(x+7) = cos(4x + 8)
i.e.
(X+7) = (4x+8)
7-8 = 4x-x
-1 = 3x
x = -1/3
