to find how many miles the car can go?? you didn't aska question but I'll assume that's what you meant. to find this multiply 17 by 32 to get 544 miles
Answer:
100
Step-by-step explanation:
100
Answer:
4x+3
How: -2x - (-6x) = 4
3 cannot be added there you go
The present dimensions are : length = 12 feet
width = 9 feet
Area = 12* 9 = 108 feet squared
If the dimensions are increased by x feet the dimensions are :
length = 12 + x
width = 9+ x
Area = ( 12+x)( 9+x)
new area = initial area * 2
( 12+ x)( 9+ x) = 2 * 108
12*9 + 12x + 9x + xx = 216
108 + 21 x + x^2 = 216
x^2+ 21x = 216-108
x^2 + 21x = 108
x^2 + 21x -108 = 0
let us plug a= 1 b= 21 c= -108 in quadratic formula
x= [-21 + / - ( 21^2 - 4* 1 * -108 )^(1/2 ]/ 2* 1
x= 4.27
Answer :
Both sides are increased by 4.27 feet .
Answer: 70!
Step-by-step explanation: set the equation equal to eachother. x=30, plug it in
