Any real number makes this equation true.
D. Start Fraction 19 over 35 End Fraction
the denominators need to be equal to add so 1/7 converts to 5/35 and 2/5 converts to 14/35
so 5/35 + 14/35 = 19/35
Answer:
5
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem
a^2+b^2 = c^2
where a and b are the legs and c is the hypotenuse
QR^2 + 12^2 = 13^2
QR^2 +144 =169
QR^2 = 169-144
QR^2 =25
Take the square root of each side
QR = sqrt(25)
QR =5
