Ответ:
x = 14.5
Step-by-step explanation:
The diagonals of a rhombus are at right angle to each other, then
∠ BOA = 90° , so
6x + 3 = 90 ( subtract 3 from both sides )
6x = 87 ( divide both sides by 6 )
x = 14.5
Ответ:
Plug in 40 to y and solve.
P=129.2
2) P=0.005y^2-0.02y+122
Plug in 132.56 for P and solve.
This came be solved by moving the terms to the left side and setting everything equal to 0. After you combine like terms and factor to get:
(y+44)=0
(y-48)=0
Y=-44 and Y=48
Age cannot be negative so the answer must be 48.
