This is one of the photos I used to answer, I’m going to send the second one
3*3+4*4=x*x and 9+16=25 so x is 5 and then add other sides so 5+8+4+5
Answer:
19/18
Step-by-step explanation:
The GCF of 9, 3, and 18 is 18.
Each denominator must be multiplied to 18, and as a result what you multiply in the denominator MUST be multiplied in the numerator.
9 * 2 = 18
1 * 2 = 2
2/18
3 * 6 = 18
6 * 2 = 12
12/18
5/18
Add all three fractions together:
12/18 + 5/18 + 2/18 = 19/18
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
Parenthasees
the first onewould evaluate to 4x²
the 2nd one would just be -2x²
