Answer:
6 cm and 8 cm
Step-by-step explanation:
Use Pythagorean theorem:
c² = a² + b²
10² = x² + (x+2)²
100 = x² + x² + 4x + 4
0 = 2x² + 4x − 96
0 = x² + 2x − 48
0 = (x − 6) (x + 8)
x = 6 or -8
x must be positive, so x = 6. Which means x+2 = 8.
C. x = 7
1 + 3 * x = 22
1 + 3x = 22
Subtract 1 from both sides.
3x = 21
Divide both sides by 3.
x = 7
The answer would be 4/10 or in simplest form it would be 2/5
Tyler made $42 commission
28% markup
$15.75 is how much he will make after raise
He pays 27.29 for the meal
Explain-$30*.15=4.5(savings). 30-4.50=25.50. 25.50*.07=1.785(rounded to 1.79). 25.50+1.79=$27.29(paid for meal)
Deal with the numbers first
GCF of 16, 40 and 68 is 4
there is no GCF of the variables
so required GCF is 4
