Answer:  -4(7g - 6h)(7g + 6h)
<u>Step-by-step explanation:</u>
Separate the 4 terms into two groups of 2 terms. Then factor out the GCF of each group. You should end up with a common factor in each group - that is one of the factors.  The other factor is what you factored out from each term.
   49g² - 36h²              - 28g - 24h 
(7g - 6h)(<u>7g + 6h</u>)          -4(<u>7g + 6h</u>)
They both have a common factor of (7g + 6h)
The terms factored out are (7g - 6h) and -4
So, the factorization is: -4(7g - 6h)(7g + 6h)
 
        
             
        
        
        
We assume , A, B, and C are angles of a triangle.
The sum of angles of a triangle is equal to 180º; therefore:
A+B+C=180º
B is 45% of angle A; then B=0.45A
C is 35% of anble A; Then C=0.35A
We can suggest this equation;
A+0.45A+0.35A=180
1.8A=180
A=180/1.8
A=100
Answer: The measurement of angle A is 100º.
