Answer:
The measure of angle 8 is 50 degrees and the measure of angle 7 is 45 degrees
Step-by-step explanation:
Area = length x width
Area = (5x + 1)*(3x - 2)
Area = 5x*3x + 5x*-2 + 1*3x + 1*-2
Area = 15x^2 - 10x + 3x - 2
Area = 15x^2 - 7x - 2 :)
Okay so the percentage of girls is 60%. in order to find the number you put
? = 60%
500 = 100%
then cross multiply, 500 * 60 is 30,000, divided by 100 is 300, there are 300 girls and 200 boys in the school. the percentage of girls is 60%
