Can somebody help me please !?
r-ruslan [8.4K]

Answer:

option 4) x = 14  y = 7

Step-by-step explanation:

We are given a side angle and a side length so we can use trigonometry to find the solution

To find x we can use sine because the given side length is opposite to the angle so,

sin(60) = \frac{7\sqrt{3} }{x}

solve for x and you get 14 (make sure you check that your calculator is in degrees)

for either use Pythagorean theorem or remove sine by tangent.

Match the reasons with the statements. GIVEN: x2 + 6x + 2x + 12 = 0 TO PROVE: x = -6 or x = -2 1. x2 + 6x + 2x + 12 = 0 Subtract
mestny [16]

Given: x^2 + 6x + 2x + 12 = 0.

1. Combining like terms (here terms 6x and 2x both contain x, then we can combine them):

x^2+(6x+2x)+12=0,\\\\x^2+8x+12=0.

2. Distributive postulate:

x^2+8x+12=(x+6)(x+2).

The equation is

(x+6)(x+2)=0.

3. Zero product postulate (zero product postulate state that if a product of two factors is equal to zero, then first factor is equal to zero or second factor is equal to zero):

x+6=0 \text{ or } x+2=0.

4. Subtraction property of equality:

a) subtract 6 from the first equation:

x+6=0\Rightarrow x+6-6=-6, \ x=-6.

b) subtract 2 from the second equation:

x+2=0\Rightarrow x+2-2=-2, \ x=-2.
