Simple..
For area, it's A=l*w
15*2=30
And, perimeter, it's P=l+l+w+w
15+15+2+2=34
Thus, your answer.
l=15 and w=2,or, w=15 and l=2
Answer:
x is 48.59
Step-by-step explanation:
sin(x)=0.75------problem
1)you need to get x alone, so inverse
x=sin^-1 (0.75)
2)plug into calculator!
Short Answer B
Argument
A
A will give you x = +/- 5i
x^2 + 25 = 0
x^2 = - 25 Take the square root.
sqrt(x^2) = +/- sqrt(-25)
x = +/- (5)i which is a complex number.
B
Is the answer
x^2 = 25
sqrt(x)^2 = sqrt(25)
x = +/- 5
C
Can't be factored just by looking at it. You can show that C is not true just by putting 5 into the equation
f(x) = x^2 + 10x - 25
f(5) = 25 + 10*5 - 25
f(5) = 50
C is not true.
D
D can be eliminated as C was
f(x) = x^2 - 5x - 25
f(5) = -25 ( l'll let you show this is not true). 5 is not a solution because it does not make f(x) = 0
