Answer:
Step-by-step explanation:
Segment BD is a leg of the right triangles. It is congruent to itself (whether or not it is marked). Angles A and C are <em>corresponding</em> acute angles in the right triangles. They are marked as congruent to each other.
The triangles are congruent by the LA theorem, applicable to right triangles. The congruency statement can be written as ...

Here in the second term I am considering 2 as power of x .
So rewriting both the terms here:
First term: 12x²y³z
Second term: -45zy³x²
Let us now find out whether they are like terms or not.
"Like terms" are terms whose variables (and their exponents such as the 2 in x²) are the same.
In the given two terms let us find exponents of each variable and compare them for both terms.
z : first and second term both have exponent 1
x: first and second term both have exponent 2
y: first and second term both have exponent 3
Since we have all the exponents equal for both first and second terms variables, so we can say that the two terms are like terms.
Answer:
A. 20
Step-by-step explanation:
- First we need find X.
- x = 7 (because we see question). f(g(7))
- Now we find g(x) = x - 3 => g(x) = 7 - 3
- Next we find f(x) = x² + x . We have f(4)
- f(4) = 4² + 4
- = 20
