Answer:
ABCD has four congruent angles.
Step-by-step explanation:
<h3>
Answer:</h3>
x=2
<h3>
Solution:</h3>
- In order to isolate x, we should first of all take the square root of both sides.
- If we take the square root of the left-hand side, we will get

- How about the right-hand side? Well, we should take the square root of the numerator (9) and the denominator (4)
- So we have

- Move -1/2 to the right:


- x=2

Answer:
8.25475 m
Step-by-step explanation:
pi*r^3 is the formula for a sphere.
Using this, pi is a nmber (about 3.14) and we only don't know the radius, but we know what it equals.
pi*r^3=1,767.1
First divide by pi, then get ride of the cube by cube rooting both sides.
The cube root of 1767.1/pi (remember to cube root both denominator and numberator!!!) is about 8.25475 m
The answer is to the question is C
Answer:
r=−5.3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−7.4r−6.31=3.23−5.6r
−7.4r+−6.31=3.23+−5.6r
−7.4r−6.31=−5.6r+3.23
Step 2: Add 5.6r to both sides.
−7.4r−6.31+5.6r=−5.6r+3.23+5.6r
−1.8r−6.31=3.23
Step 3: Add 6.31 to both sides.
−1.8r−6.31+6.31=3.23+6.31
−1.8r=9.54
Step 4: Divide both sides by -1.8.
−1.8r/−1.8=9.54/−1.8
r=−5.3
