Mathematics
1 answer:
galina1969 [7]3 years ago
6 0

Answer:

x=9                   x=-1

Step-by-step explanation:

2(x-4)^2=50

Divide each side by 2

2/2(x-4)^2=50/2

(x-4)^2=25

Take the square root of each side

sqrt((x-4)^2)=sqrt(25)

x-4 = ±5

x-4 =5            x-4 = -5

Add 4 to each side

x-4+4=5+4    x-4+4 = -5+4

(13p5 + 6p - 12p2) - (-9p - p2 - 13p5)
anastassius [24]

Answer:

Step-by-step explanation:

13p⁵ + 6p - 12p² -(-9p - p² - 13p⁵) = 13p⁵ + 6p - 12p² + 9p + p² + 13p⁵

{Distribute  (-1) to the second expression}

= <u>13p⁵ + 13p⁵</u>    <u>-12p² + p²</u>     <u>+ 6p + 9p</u>

{Combine like terms}

= 26p⁵ - 11p² + 15p

WILL GIVE BRAINLIEST..... NEED HELP FAST
Setler79 [48]

Answer:2516 pounds

Step-by-step explanation:

find the difference in gallons and the difference in the weights

46 - 14 = 32 gallons

2399 - 2191 = 208 pounds

 so 32 gallons of gas weighs 208 pounds

find weight per pound: 208 pounds / 32 gallons = 6.5 pounds per gallon

 round to 6.5 pounds per gallon

64 gallons - 46 gallons = 18 gallons

 18 gallons x 6.5 pounds per gallon = 117 pounds

2399 + 117 = 2516  weight of plane with 64 gallons
