−2(6x+5)=74
Simplify both sides of the equation.
−2(6x+5)=74
−2 x 6x−2 x 5=74
−12x−10=74
Add 10 to both sides.
−12x−10=74
+10 +10
−12x=84
Divide both sides by -12.
−12x
=
84
/−12 /-12
x=-7
hope it helps!

Answer:
No
Step-by-step explanation:
Triangular Inequalities state that in a triangle, the sides must always be less than the sum of the other two.
You would have sides x, 2x, 3x in this case and use the inequality a+b>c.
if...
a=x, b=2x, c=3x
then...
x+2x>3x
3x>3x which is false.
Therefore you cannot make a triangle with sides proportional to 1, 2, and 3.
Answer:
14.13 ft²
Step-by-step explanation:
The area of a semicircle is
We were given the radius of the semicircle to be: r=3 feet.
We were also asked to use π as 3.14.
We substitute into the formula to get:
This is the same as:
Or
The area of the semicircle is 14.13 ft²
