Given:
Rectangle shape.
Length is 3 feet longer than its width
Width is unknown let it be x.
Perimeter is 26 feet
Perimeter = 2Length + 2Width
26 ft = 2(x+3) + 2x
26 ft = 2x + 6 + 2x
26 ft = 4x +6
26 ft - 6 = 4x
20 ft = 4x
20 ft / 4 = x
5 ft = x
The width is 5 feet.
Length is 3 ft longer than the width. Thus, it is 8 feet.
To check:
perimeter = 2L + 2W
26 ft = 2(8ft) + 2(5ft)
26 ft = 16 ft + 10ft
26 ft = 26 ft
Answer:
b=7/33 c= 14/33
Step-by-step explanation:
Repeat all 21 they are repeating decimals
for b its 100x-x=21.21 repeating the 21 -0.21 repeating the 21 = 100x-1x=(21+0.21)-0.21= (100-1)x=21+0.21-0.21 [ stop repeating the 21's up to here] and 99x=21+0 = 99x=21 = 99x/99=21/99 both 99's cancel leaving 3x7 divided by 3x33 = x= cancel both 3's leaving 7 over 33 This should help you learn to solve c good luck

amount financed=cash price-down payment.
Step-by-step explanation:
Here there's a logic.
Answer:
y = 2x - 13
Step-by-step explanation:
Equation of a line is y = mx + c, m is the gradient and c is the intercept
The line passes through points 4 and -5, x is 4 and y is -5
-5 = 4m + c
When two lines are perpendicular, the products of their gradients are equal to -1, m1 * m2 = -1
x + 2y = 5
2y = -x + 5
y = (-1/2 * x) + 5
therefore m = -1/2
m1 * m2 = -1
m * -1/2 = -1
-m = -2 , therefore m = 2
-5 = 4 * 2 + c
c = -5 - 8, which is -13
Therefore the equation for the line is
y = 2x - 13
