Answer:
Expand
2b + 3 = 2 -3b -9
Correct like terms
2b + 3 = 3b - 7
Move 2b to the otherside as a negative number and -7 to the otherside positive number.
-4 = -5b
Divide both sides by negative five
b is equal to 4/5
Step-by-step explanation:
<em>h</em><em>o</em><em>p</em><em>e</em><em> </em><em>i</em><em>t</em><em> </em><em>h</em><em>e</em><em>l</em><em>p</em><em>s</em><em> </em><em>y</em><em>o</em><em>u</em><em> </em><em>!</em><em>!</em>
So if the perimeters are equal then you know
Rectangle Triangle
x + x + x + 4 + x + 4 = x + x + 9 + x + 5
which becomes
4x + 8 = 3x + 14
now you can solve the equation for x, then find the perimeters

Answer:
what are we doing like is it order of operations??
Step-by-step explanation:
lmk what it is
Distance Firework B would have traveled after 0.25 seconds:
240 x 0.25 = 60 feet
Let x be the time that it will explode together:
60 + 240x = 340x
100x = 60
x = 60 ÷ 100
x = 0.6 sec
Firework A will explode at 0.6 seconds after it is launched
Firework B will explode at (0.6 + 0.25) 0.85 seconds after it is launched.
-------------------------------------------------------------------------------------------------
Answer: Firework B will explode at 0.85 seconds after it is launched.
