Answer:
x=3
Step-by-step explanation:
You can solve by:
5x+7=-3x-31
adding 3x to each side:
8x+7=31
Subtract 7 from each side:
8x=24
Divide each side by 8:
x=3
That is your answer
Hope this helps!
−3(1+x)=−3x+1
Step 1: Simplify both sides of the equation.
−3(1+x)=−3x+1
(−3)(1)+(-3)(X)=-3x+1
(Distribute)
−3+ −3x=−3x+1
−3x−3=−3x+1
Step 2: Add 3x to both sides.
−3x−3+3x=-3x+1+3x
−3=1
Step 3: Add 3 to both sides.
−3+3=1+3
0=4

Answer:
2139m (total area)
Step-by-step explanation:
I am like 98% sure this is right
23* 31= 713 (1 side area)
713+713=1426 (2 sides area)
31-12=19 (middle height)
19*23= 437 (middle area)
437+1426=2139m (total area)
