Let x be the length of the shortest side. second side is 5+x and the last is 2x-5. add these three to get the perimeter 64
x+5+x+2x-5=64
4x=64
x=16
sides are 16, 21, and 27

Solves the following equation for a. Show steps for full credit.<br> 4a + 10 = 2a + 26
Kay [80]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{a = 8}}}}}

Step-by-step explanation:

\sf{4a + 10 = 2a + 26}

Move 2a to left hand side and change it's sign

Similarly, move 10 to right hand side and change it's sign

⇒\sf{4a - 2a =26 - 10}

Collect like terms

⇒\sf{2a = 26 - 10}

Subtract 10 from 26

⇒\sf{2a = 16}

Divide both sides of the equation by 2

⇒\sf{ \frac{2a}{2}  =  \frac{16}{2} }

Calculate

⇒\sf{a = 8}

Hope I helped!

Best regards!!
