Answer:

X=5

3.18x +2.6 +0.9x +x= 28

5.08x+2.6 =28

-2.6. -2.6

5.08x= 25.4

5.08÷5.08 =x

25.4÷5.08=5

EXPAND THE POLONOMIAL <br><br> (5a+1/2b)^2 HELPPP ASAP

stepan [7]

Answer:

25 $a^{2}$ +5ab+ $\frac{b^{2} }{4}$

Step-by-step explanation:

$(5a+\frac{1}{2} b)^{2}$

1. First, write out the expression without the square

$(5a+\frac{1}{2} b)(5a+\frac{1}{2} b)$

2. Then use foil to multiply:

5a*5a+5a* $\frac{1}{2}b$ + $\frac{1}{2}b$ *5a+ $\frac{1}{2}b$ * $\frac{1}{2}b$

=25 $a^{2}$ +5ab+ $\frac{b^{2} }{4}$

3. That is your answer.
