Answer:
L = 48
Step-by-step explanation:
Given that L varies directly with Z² , then the equation relating them is
L = kZ² ← k is the constant of variation
To find k use the condition L = 12 when Z = 2 , then
12 = k × 2² = 4k ( divide both sides by 4 )
3 = k
L = 3Z² ← equation of variation
When Z = 4 , then
L = 3 × 4² = 3 × 16 = 48

Hello, Oliveria. I am saddened to hear that you have started a whole rewrite of your plan for mathematics, but fear not; there are a couple of resources and websites that are always ready for you. For starters, visit websites that have at least 7th or 6th grade and up in benchmark mathematics content; this would be IXL, KhanAcademy, or even take some of the lesson tutorials from places like Symbolab and mathpoppa (<span>please, don't use the algebra calculator a lot. It will add more to your demise). Any how, you can always ask your guidance counselor at your school for help, or even your algebra teacher for some tutorials on certain topics. Always at least try to ask for help from your teacher or friends; even if you think they can't help much, it is always best to try
It seems that you have enough self direction and initiative to go on this route, now you just need the additional boosts :)</span><span />
Answer:
469.25
Step-by-step explanation:
peter=x
david=x+1.50
x+(x+1.50)=940
x=940-x-1.50
2x=940-1.50
2x=938.5
x=938.5/2
x=469.25
