Answer:

(a + b) (a + b) = 35

Step-by-step explanation:

{(a + b)}^{2}  =  {a}^{2}  +  {b}^{2} + 2ab \\  \\ (a + b)  (a + b)  = a \ast a + b \ast b + 2ab \\  \\  = 25 + 2 \times 5 \\  \\ 25 + 10 \\  \\  (a + b)  (a + b)  = 35

68/80 as a fraction,percent,and decimal
madam [21]
68/80 is a fraction
34/40
17/20 is simplest form of fraction

percent means parts out of 100 so x/100
20 times 5=100 so
17/20 time 5/5=x/100=85/100 or 85%

decimal is normally a power of 10 so
85/100=0.85

What is the area of the figure?
son4ous [18]
Yes. 95 is correct.
You have three congruent "indentations" in the right hand side. Thus each section must be 15/3 = 5 cm long.
The top rectangle will be 8*5 = 40 cm^2
The bottom rectangle will also be 8*5 = 40 cm^2
The middle area will be 5(8-5) = 5 * 3 = 15 cm^2
40 + 40 + 15 = 95
