Answer:
width = 2.4
Step-by-step explanation:
so we know that the formula to get an area of a square/rectangle is A=lw, where <em>A </em>is the<em> </em><em>area</em><em>, </em><em>l</em><em> </em>is the<em> </em><em>length</em><em>, </em>and <em>w</em> is the <em>width</em><em>.</em>
we already have the area and the length, so all we need now is the width.
to find the width, simply plug in the area and the length into the formula, which will give you:
A = lw <em>-given formula</em>
12 = 5(w) <em>-plug in known variables</em>
12/5 = 5w/5 <em>-divide both sides by 5 to get x by itself</em>
2.4 = w <em>-turn the fraction into decimal if you prefer it that way</em>
<em>possible answers: </em><u><em>w = 2.4</em></u>, <em><u>w = 12/5</u></em>, or <u><em>w = 2 2/5</em></u>
Answer:
the length is 18.4
Step-by-step explanation:
We are asked to determine the value of a such that the function f(x) = ax^2 + 5 is fit for the point given (-1,2). In this case, we substitute 2 to y and -1 to x. The result is then 2 = a*(-1)^2 + 5 ; 2 = a + 5; a is then equal to -3
Answer:
Im pretty sure its 7 but wait for someone else to awnser id.k if i did my math correctly or not lol
Step-by-step explanation:
Put x and y on one side.
y = -3/10x - 8
Add 3/10x to both sides.
3/10x + y = -8
Because there are no fractions in Standard Form, multiply everything by 10.
3x + 10y = -80
