Step-by-step explanation:
a)
put the formula....
l × b = A
or,
or,
or,
Therefore,
b)
we know the value of x,
l = 4x-3 b = x+2
= 4× 11 -3 = 11+2
= 41cm = 13cm
Area= l × b
= 41 × 13
= 533 cm^2
c)
square = l × l
Given,
121x^2 - 22x + 1
or, 121x^2 -11x -11x +1
or, 11x ( 11x -1 ) - 1 ( 11x -1 )
Therefore,
dimension is ( 11x-1 )( 11x -1 )
d) x= 25
l= 11x -1
= 11× 25 -1
= 274cm
Area= l^2
= 75076 cm^2
Area of frame = (12cm)^2
= 144cm^2
Area of painting= ( 1225-144 )cm^2
= 1081 cm^2
(length)^2 = Area
or, l^2 = (1081)
or 1^2 = (32.8)^2
Therefore, dimension of painting is 32.8cm
Answer:
Thats Wrong , Its (16, -8) faCCts
Step-by-step explanation:
Yes, $4 million is correct, great job!
To make sure you are correct, just plug in 2 for every time x appears.
2^2-6(2)+12
4-12+12
4-0 =
4
Yep, since this is represented in millions of dollars, 2 years makes the result $4 million, which is the goal.
Great work! Let me know if you need anything else! :)
Answer:
$17.50
Step-by-step explanation:
Multiply 7/8 by 20/1, to find 7/8 of $20.00.
7/8 × 20/1 = 140/8
140 ÷ 8 = 17.5
Once you convert to money, this is $17.50.
