Answer: Adiya’s method is not correct. To form a perfect square trinomial, the constant must be isolated on one side of the equation. Also, the coefficient of the term with an exponent of 1 on the variable is used to find the constant in the perfect square trinomial. Adiya should first get the 20x term on the same side of the equation as x2. Then she would divide 20 by 2, square it, and add 100 to both sides.
The answer is 2 miles or 3520 yards. (they are the same answer.)
If this helps, can you give me the brainliest answer? I need it...
Thank you very much.
<span> 0.81x - 0.45 is subtracted from 3.28x + 1.4
</span>3.28x + 1.4 - (0.81x - 0.45) = 3.28x + 14 - 0.81x + 0.45
= (3.28x - 0.81x) + ( 14 +0.45)
= 4.09x + 14.45
3/5 of 1600 = $960 spent for heavy duty tapes
1600 - 960 = $640 spent for regular tapes
The company normally bought
960 ÷ 30 = 32 heavy duty tapes
640 ÷ 20 = 32 regular tapes
With the new prices, the company is paying
32 × 28 = 896 for the heavy duty tapes
32 × 19 = 608 for the regular tapes
The company is saving
960 - 896 = $64 for the heavy duty tapes
640 - 608 = $32 for the regular tapes
