Answer:
difference in area = 16 ft²
if you use 8 the difference in length between Jack patio and his neighbor patio will be will be 15 - 13 = 2 ft
if you use 13 the difference i length will be 25 - 18 = 7 ft
Step-by-step explanation:
Jacks rectangular patio
width = a
length = 2a - 1
area = lw
where
l = length
w = width
area = 120 ft²
a(2a - 1)
2a² - a - 120 = 0
(a - 8) (2a + 15)
a = 8 or -15/2
Ron's rectangular patio
width = a
length = a + 5
area = lw
area = 104 ft²
a (a + 5) = 104
a² + 5a -104 = 0
(a + 8) (a - 13)
a = -8 or 13
How many square feet longer is jack patio longer than Ron's patio is the difference in their area. Therefore,
120 - 104 = 16 ft²
The value 8 or 13 can be used for a since the width a have to be the same.
if you use 8 the difference in length between Jack patio and his neighbor patio will be will be 15 - 13 = 2 ft
if you use 13 the difference i length will be 25 - 18 = 7 ft
The solution to the system of equation is (1, 4).
In order to find this, we can first just see where the graphs intersect each other. This will give us the solution set.
As for what it represents, the x value in the increase in temperature and the y value is the increase in customers.
Therefore, we know that we want the temperature to go up by 1 (although we don't know the units) and that would result in the amount of people coming, and staying longer by 4 (again, we don't know the units of measure).
Answer:
5 3/7
Step-by-step explanation:
On this one all you basically have to do is 4+1 since they are both whole numbers, then attatch the fraction onto that.
4+1=5
5 3/7
Answer:
-10
Step-by-step explanation:
f(-4)=-(-4)-5
f(-4)=-1
g(-6)=2(-6)+3
-12+3
g(-6)=-9
add together:
-1+-9
=-10
In this case it's, <span>log(u)^n = nlog(u)
so the answers are either </span><span>4 log (3x) or it could also be </span><span>4[log3 + log x]
</span>There is no need for the solution to be shown because this is a simple rule of properties of logarithms
