To solve for variable equations or inequalities, we want to do two things:
1. Reduce one side to variables only
2. Reduce that side to the variable without coefficients.
The given equation is
.
Let's perform step 1: reducing one side to variables only. By adding
to both sides of the equation, we get
.
Now let's perform step 2: reducing that side to the variable without coefficients. Since the coefficient of
is
, we need to divide both sides of the equation by 4:
. Rounded to the nearest tenth,
.
So the value of
that satisfies
is
.
Answer:
normally i would but i think it will be better if you did it yourself. i mean you can always use a calculator

Answer:
86 cm²
Step-by-step explanation:
<u>1) Calculate the area of the square</u>
Therefore, the area of the square is 400 cm².
<u>2) Calculate the area of the circle</u>
we can substitute with 3.14. To find the radius, we divide the diameter of the circle by 2. 20 cm is the diameter of the circle, so therefore, its radius is 10 cm.
Therefore, the area of the circle is 314 cm².
<u>3) Subtract the area of the circle from the area of the square</u>
Therefore, the area of the shaded region is 86 cm².

To factor the trinomial, you can use the ac method where you multiply the first and last terms together (6 and 9) and add up to 15.
In this case ac= 54
2 numbers that multiply to 54 and add up to 15 would be 6 and 9 so place these numbers where the 15 would be:
Then group terms to simplify:
Simplify any like terms:
And group together again:
You can simplify a 3 out of the first expression one more time to get:
Which would be the factored form. I hope this helps :)
Answer:
C
Step-by-step explanation:
