Answer:
Cannot be factored further.
Step-by-step explanation:
I'm just gonna pretend that the equal sign isn't there.
First, simplify the numbers. when you simplify, you should get 7x^2-64.
This is the final. Your answer should be it cannot be factored further.
Answer:
They are 5 I think
Step-by-step explanation:
It should be correct
Answer:
Step-by-step explanation:
BD is opposite the 30° angle. The sine of 30° is 0.5. The sin of an angle in a right triangle is opposite/hypotenuse so BD = sin 30°x8.
Now you have two known lengths The third can be found by applying the Pythagorean theorem: BC²+BD²=CD², from which you can establish a numerical value for BC.
