Answer:
2/3,4/3.
Step-by-step explanation:
<span>Equation at the end of step 1 :</span><span> (((4•(a2))•b)-((8•(a3))•(b5)))+2ab7</span><span>Equation at the end of step 2 :</span><span><span> (((4•(a2))•b)-(23a3•b5))+2ab7
</span><span> Step 3 :</span></span><span>Equation at the end of step 3 :</span><span> ((22a2 • b) - 23a3b5) + 2ab7
</span><span>Step 4 :</span><span>Step 5 :</span>Pulling out like terms :
<span> 5.1 </span> Pull out like factors :
<span> -8a3b5 + 4a2b + 2ab7</span> = <span> -2ab • (4a2b4 - 2a - b6)</span>
Trying to factor a multi variable polynomial :
<span> 5.2 </span> Factoring <span> 4a2b4 - 2a - b6</span>
Try to factor this multi-variable trinomial using trial and error<span>
</span>Factorization fails
Final result :<span> -2ab • (4a2b4 - 2a - b6)

Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
Not really
Step-by-step explanation:
NOT NECESSARILY would a triangle be equilateral if one of its angles is 60 degrees. To be an equilateral triangle (a triangle in which all 3 sides have the same length), all 3 angles of the triangle would have to be 60°-angles; however, the triangle could be a 30°-60°-90° right triangle in which the side opposite the 30 degree angle is one-half as long as the hypotenuse, and the length of the side opposite the 60 degree angle is √3/2 as long as the hypotenuse. Another of possibly many examples would be a triangle with angles of 60°, 40°, and 80° which has opposite sides of lengths 2, 1.4845 (rounded to 4 decimal places), and 2.2743 (rounded to 4 decimal places), respectively, the last two of which were determined by using the Law of Sines: "In any triangle ABC, having sides of length a, b, and c, the following relationships are true: a/sin A = b/sin B = c/sin C."¹
