Answer:
y=1/2x+3
Step-by-step explanation:
-subtract 2y from both sides
-divide 2 from both sides
L*W=51
L=W+4
Replace L with W+4: (W+4)*W=51
W²+4W-51=0
use the quadratic formula to find W:5.4 (sorry cannot type the formula here)
the length is 5.4+4=9.4
Answer:
<u>Answer</u><u>:</u><u> </u><u>w</u><u> </u><u>is</u><u> </u><u>1</u><u>.</u><u>6</u><u> </u><u> </u><u>or</u><u>. </u><u>-</u><u>5</u><u>.</u><u>6</u><u> </u>
Step-by-step explanation:
• I guess the question asks to find the value of w
• arrange the equation in a quadratic equation format. i.e; ax² + bx + c = 0
• let's solve the equation using the quadratic formular
• Substitute following the mathematical operation rules:
• split the result:
