If we work out this particular equation according to the acronym PEMDAS
(or parenthesis, exponents, multiplication, division, addition, subtraction) this can be easily done. The resulting equation would look
as follows PEMDAS2(3)2+16(2)+112+112+1=13

Answer:
x² +11x +28
Step-by-step explanation:
(x +4) (x+7)
take the first x and multiply by x and then the 7 which gives you x² +7x
then take the 4 and multiply it by the x and the 7 which gives you 4x + 28
add all like terms
8/x = 2/5
cross multiply
(2)(x) = (8)(5)
2x = 40
x = 40/2
x = 20
now check out ur fractions : 8/20 = 2/5....notice that they are equivalent fractions...just like proportions...nothing but equivalent fractions
Answer:
(15°, 165°)
Step-by-step explanation:
Given the equation 6 sin2(x) = 3, we are to find the value of x that satisfies the equation in the interval [0, 2π]
Given
6 sin2(x) = 3,
Divide both sides by 6
6 sin2(x)/6 = 3/6
sin2(x) = 1/2
2x = sin^-1(0.5)
2x = 30°
x = 30°/2
x = 15°
Since sin is positive in the second quadrant, x2 = 180-15
x = 165°
Hence the values within the interval are 15 and 165.
(15°, 165°)
It is blury. take an anther pic please
