Answer:
Step-by-step explanation:
The number inside the square root symbol is the number you have to get when you multiply a certain number twice.
So :
What multiplied by itself is 121?
Backwards equation:
Do not do the backwards method all the times, it does not work for all numbers.
To find surface area, we can use the equation:
SA=2lw+2wh+2lh, where:
l=10 in
w=3 in
h=7 in
SA=(2)(10)(3)+(2)(3)(7)+(2)(10)(7)
SA=60+42+140
SA=242 in²
Answer:
if sin (x-3) degrees = cos (2x+6) degrees, find the value of x.
----------
Note: sin and cos are complementary functions....
sin(x) = cos (90-x)
-------------------
Your Problem:
sin(x-3) = cos(90-(x-3))
Equation:
90-[x-3] = 2x+6
90-x+3 = 2x+6
3x = 93-6
x = 31-2
x = 29
