Area of a Square Formula: A = s²
- <em>s</em> is a side length
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
A = 124 in²
<u>Step 2: Solve for </u><em><u>s</u></em>
- Substitute in variables [Area of a Square Formula]: 124 in² = s²
- [Equality Property] Square root both sides: s = 2√31 in
- Approximate: s = 11.1355 in
Answer:
Option a.
Step-by-step explanation:
You have the following limit:
The method of direct substitution consists of substituting the value of in the function and simplifying the expression obtained.
We then use this method to solve the limit by doing
Therefore:
By definition, any number raised to exponent 0 is equal to 1
So
Finally
Answer:
x=340
y=-165
Step-by-step explanation:
x/10+y/5=1 Equation 1
x/8+y/6=15 Equation 2
Using elimination method, we multiply equation 1 by 1/6, the coefficient of y in equation 2 and then also multiply equation 2 by 1/5, the coefficient of y in equation 1, this will make you have the same coefficient and then easy to eliminate.
1/6(x/10+y/5=1)
x/60+y/30=1/6 Equation 3
1/5(x/8+y/6=15)
x/40+y/30=15/5
x/40+y/30=3 Equation 4
We subtract equation 3 from equation 4 to eliminate y
x/40-x/60= (3x-2x)/120= x/120
y/30-y/30
3-1/6= (18-1)/6= 17/6
We now have
x/120=17/6
Cross multiply
6x=2040
Divide both sides by 6
6x/6=2040/6
x=2040/6
x=340
Substitute x for 340 in equation 1
x/10+y/5=1
340/10+y/5=1
34+y/5=1
y/5=1-34
y/5=-33
Cross multiply
y=-33(5)
y=-165
