Arectangular picture frame is 5 inches wide and 10 inches tall. you want to make the area 6 times as large by increasing the length and width by the same amount. find the number of inches by which each dimension must be increased.

Step-by-step explanation:

let length and width be increased by x>0

(10+x)(5+x)=6×10×5

50+10 x+5x+x²=300

x²+15x-250=0

x²+25 x-10x-250=0

x(x+25)-10(x+25)=0

(x+25)(x-10)=0

x=-25(rejected),10

so x=10

so both the dimensions should be increase by 10 inches.

it is 10 inches

Step-by-step explanation:

15 batches are the most you can make

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
