Answer:
s = 6 cm
Step-by-step explanation:
The area (A) of an equilateral triangle is calculated as
A = ( s is the length of side )
Here A = 9 , thus
= 9 ( multiply both sides by 4 to clear the fraction )
s² = 36 ( divide both sides by )
s² = 36 ( take the square root of both sides )
s = = 6
Answer:
(-infinity, -4) ∪ (-4, 6) ∪ (6, +infinity)
Step-by-step explanation:
Any domain restrictions here stem only from division by zero. Thus, we take the denominator, g^2−2g−24, and purposely set it to 0, and solve for g:
g^2−2g−24 = 0 => (g-6)(g+4) = 0. Solving for g, g=6 and g= -4.
This function is defined for all values of g other than 6 and -4. We could also write the domain as follows: (-infinity, -4) ∪ (-4, 6) ∪ (6, +infinity).
Hey there! I'm happy to help!
We want to find how much money the lunch meat costs for one pound. We see that it costs $42.50 for 5 pounds, so we simply divide by 5 to see how much it costs for 1 pound.
42.5/5=8.5
Therefore, the answer is D. $8.50 per pound.
Have a wonderful day! :D
Let's break down all the information we receive from the question.
One pair of shoes= three times as much as a scarf
One pair of shoes and one scarf= $32
We need to make an equation where 3s= pair of shoes and s=scarf. We then need to put one pair of shoes + one scarf = 32.
3s+s=32
Now add.
4s=32
You could use 4s=32 (or 32÷4=s).
