Write an equivalent expression for 88 +16x +8 . If x=4,is the solution to both expressions the same.
Firlakuza [10]
You can find an equivalent expression for this by combining like terms.
The terms are 88, 16x, and 8.
The like terms are 88 and 8.
To combine them, add them together.
88 + 8 = 96
The equivalent expression would be 16x + 96.
This means 16x + 96 is the same as <span>88 + 16x + 8.

Since they are equivalent, that means they are equal, or the same.
So no matter what x is, they will both be equal to the same thing, so their solutions will be the same.

Answers:
Equivalent Expression: 16x + 96
Yes, both expressions will have the same solutions if x = 4.

Can someone explain to me or help me get an intuition for why phi = 2 * theta in this case? Why is this property always true?
Alenkasestr [34]
This is obtuse ?

let phi =  135

2theta = 180 -135 = 45

theta = 22.5

phi != 2 * 22.5 != 45

Did you mean ?

phi = 180 - 2theta

Can you provide more explanation ?

Тhe third angle of the triangle = 90 - 60 = 30°

In a 30-60-90  triangle the side opposite the 30 degree angle is half the length of the hypotenuse, therefore y = \frac{8 \sqrt{3} }{2}=4 \sqrt{3}

x=8 \sqrt{3} \cdot \cos30^o =8 \sqrt{3} \cdot { \frac{ \sqrt{3} }{2} } =12

The answer is x = 12, y = 4√3
