What is the product of the binomials below?
Otrada [13]

Answer:

The correct answer is 8x^2+28x+20.

Step-by-step explanation:

(2x+5)(4x+4)

Multiply the first bracket with each element of second bracket:

=4x(2x+5)+4(2x+5)

=8x^2+20x+8x+20

Now solve the like terms:

=8x^2+28x+20

Thus the correct answer is 8x^2+28x+20....

Precalculus PLEASE HELP ME right answers only check all please
Alex_Xolod [135]

Given :

cos(x)cos(\frac{\pi }{7}) + sin(x)sin(\frac{\pi }{7})=-\frac{\sqrt{2}}{2}

We know the identity

cos(x)cos(y) + sin(x)sin(y)=cos(x-y)

We use this property to simplify the left hand side

So  cos(x)cos(\frac{\pi }{7}) + sin(x)sin(\frac{\pi }{7})=cos(x - \frac{\pi }{7})

cos(x - \frac{\pi }{7}) =-\frac{\sqrt{2}}{2})

we know ,

when cos(x) =-\frac{\sqrt{2}}{2}) then

x = \frac{3\pi }{4} , \frac{5\pi }{4}

For  cos(x - \frac{\pi }{7}) =-\frac{\sqrt{2}}{2})

x - \frac{\pi }{7}= \frac{3\pi }{4} and x - \frac{\pi }{7}= \frac{5\pi }{4}

Add \frac{\pi }{7} on both sides

x= \frac{3\pi }{4} + \frac{\pi }{7} and x= \frac{5\pi }{4} +\frac{\pi }{7}

Finally we add 2npi for general solution

So options C  and D  are correct

What is the correct method of solving the equation x/3-6=9 for x?
AveGali [126]

Answer: The value of x is 45

Step-by-step explanation:

The equation x/3-6=9 is a linear equation, where x/3 is the same as one-third of x.

Thus it is easily simplified as such:

x/3-6=9

Collect like terms

x/3 = 9 + 6

x/3 = 15

i.e (1/3) of X = 15

To get the value of x, cross multiply

x = 3 x 15

x = 45

Thus, the value of x is 45
