I do not know how to do this but i can tell you ^ means exponent not division. So 3^2 would be the same as
X=number1 and y=number2
product of the two numbers is 14 which translates to
xy=14
either x or y are 3.5 times big as the other one
so 3.5x=y
substituting in xy=14
x(3.5x)=14
then x must be equal to 2 or -2
x+y=
by substituting
x+3.5x=
if x =2 then 2+7=9 or if x=-2 then -2-7=-9
Answer:
Step-by-step explanation:
You can’t just substitute 0 for θ. 0 is a constant, not a variable.
secθ = -13/5
cosθ = 1/secθ = -5/13
sin²θ = 1 - cos²θ = 144/169
sinθ = -12/13
cscθ = 1/sinθ = -13/12
tanθ = sinθ/cosθ = 12/5
cotθ = 1/tanθ = 5/12
Check the picture below.
since the pyramid has 4 triangular faces and a square base, let's add their areas together and that'd be the area of the pyramid.
<span>-9 -10[7x -3(3 + 10x)]
= -9 - 10(7x - 9 - 30x)
= -9 - 10( -23x - 9)
= -9 + 230x + 90
= 230x + 81
Answer: </span>230x + 81<span>
</span>
