Answer:
Step-by-step explanation:
Answer: 9x^4
Using the rules of exponents multiply the -3 times the -3 which equals 9 canceling out the negatives. Then you have that other ^2 but you also had the other one so you still have to keep it which equals that ^4.
Answer:
CU = 117
Step-by-step explanation:
Since we have similar triangles, we can use proportions. Put the small triangle sides over the large triangle side.
WC WD
----------- = -------------
WU WV
26 20
----------- = -------------
36x-1 110
Using cross products
26*110 = 20* (36x-1)
Distribute
2860 = 720x - 20
Add 20 to each side
2860+20 = 720x-20+20
2880 = 720x
Divide by 720
2880/720 = 720x/720
4=x
We need to find CU
CU = WU - WC
Substituting in what we know
CU = 36x-1 -26
Since we know x=4
= 36*4 -1 -26
144 - 27
= 117
Honestly just use a calculator
Answer:
<u>180 miles</u>
Step-by-step explanation:
- Ann's car can go 288 miles on 8 gallons
<u>Base rate</u>
- = No. of miles / No. of gallons
- = 288 / 8
- ⇒ 36 miles per gallon [Important to rememeber!]
<u>5 gallons</u>
- Distance for 5 gallons = base rate x 5
- Distance = 36 x 5
- Distance = <u>180 miles</u>
