Answer:
x^2 + 5x - 84 = 0
x = 7
Step-by-step explanation:
let the sister's age = y
sister's age (y) = 5 + x equation 1
xy = 84 equation 2
Make y the subject of the formula in equation 2
y = 84/x
equate equation 1 and 2
84/x = 5 + x equation 3
Multiply equation 3 by x
84 = 5x + x^2
x^2 + 5x - 84 = 0
tjis can be solved using quadratic equation
x^2 -7x + 12x -84 = 0
x(x + 12) -7(x + 12)
x = 7 or - 12
age cant be negative so his age is 7
The diagram shows how the surface area can be "flattened" into two rectangles, one for the end triangles that is 6 cm by 5.3 cm, and one for the lateral area that is 13 cm by 19.3 cm.
The total area is
.. (6 cm)*(5.3 cm) +(13 cm)*(19.3 cm)
.. = 31.8 cm^2 +250.9 cm^2
.. = 282.7 cm^2
Answer:
1. 44
2. 73
Step-by-step explanation:
1:
1/2 (7) (4) + 6 (5) =
1/2 (28) + 30 =
14 + 30 =
44
2:
12 (6) + 1/4 (2^2) =
72 + 1/4 (4) =
72 + 1 =
73
