The two numbers are <u>11 and 77.</u>
<h3>
EXPLANATION</h3>
The ratio between the first and second number is 1:6, meaning that 1/7 of 84 is the first number, and the remaining 6/7 is the second number.
84 ÷ 7 = <u>11</u>
84 - 11 = <u>77</u>
The expression for the area of frame is 4x² + 24x + 35
<h3>What is Area of rectangle?</h3>
Area of rectangle is the region occupied by a rectangle within its four sides or boundaries. The area of a rectangle depends on its sides.
Here, Old length of photograph = 5 inch
Old width of photograph = 7 inch
Now, length of new photograph = (5 + 2x) inch
width of new photograph = (7 + 2x) inch
Now, Area of frame with new dimension = Length X breadth
= (5+2x) X (7+2x)
= 5(7+2x) + 2x(7+2x)
= 35 + 10x + 14x + 4x²
= 4x² + 24x + 35
Thus, the expression for the area of frame is 4x² + 24x + 35.

Answer:
QR = 13.3
Step-by-step explanation:
We solve using Pythagoras Theorem
c² = a² + b²
RP² = PQ² + QR²
QR² = RP² - PQ²
QR = √RP² - PQ²
RP=15
PQ=7
QR = √15² - 7²
QR = √(176)
QR = 13.266499161
Approximately = 13.3
Therefore, the length of QR = 13.3
