To solve this equation, we have to use the distributive property to multiply 5y through the parentheses.
-45y - 15y^2 = 13
-15y^2 - 45y - 13 = 0
15y^2-45y-13=0
<span>y=<span><span>32</span>+<span><span><span><span>130</span><span>√2805</span></span><span> or </span></span>y</span></span></span>=<span><span>32</span><span><span><span>−1</span>30</span><span>√<span>2805, when you use the quadratic formula.</span></span></span></span>
This statement would be incorrect because 0.086 equals 8% because you move the decimal place to the right two spaces.
1.71 is your answer hope this helps
Lets x = KB
2/5 = 3/(x+3)
2(x+3) = 3(5)
2x+6 = 15
2x = 9
x = 4.5
answer
KB = 4.5 cm
