Answer:
65.97 - Circumference
346.36 - Area
Sorry if this was incorrect ^^'
5=−(−z+3)
Simplify:
5=−(−z+3)
5=z+−3(Distribute)
5=z−3
Flip the equation.
z−3=5
Add 3 to both sides.
z−3+3=5+3
z=8
Answer:
A ≈ 5.6
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = 
× PQ × PR × sin P
= 0.5 × 5.2 × 2.8 × sin50°
≈ 5.6 ( to 1 dec. place )
Answer:
2x + 2x+2 = 3x + 1
4x + 2 = 3x + 1
Subtract 3x from both sides
4x - 3x + 2 = 3x - 3x + 1
x + 2 = 1
Subtract 2 from both sides
x + 2 - 2 = 1 - 2
x = -1
Hope this helped!!!

Substitute y = 2x - 4 to x + 2y = 12:
x + 2(2x - 4) = 12 <em>use distributive property</em>
x + (2)(2x) + (2)(-4) = 12
x + 4x - 8 = 12 <em>add 8 to both sides</em>
5x = 20 <em>divide both sides by 5</em>
x = 4
Put the value of x to the first equation:
y = 2(4) - 4
y = 8 - 4
y = 4
<h3>Answer: x = 4 and y = 4</h3>
