Answer:
Step-by-step explanation:
Perimeter of a rectangle = 2L +2W
L is the length
W is the width
If the length of a rectangle is 2 cm less than 7 times the width, then;
L = 7W-2 .... 2
Substitute eqn into the formula for finding the perimeter
P = 2(7W-2)+2W
P = 14W-4+2W
P = 16W-4
If P =60cm
60 = 16W-4
16W = 60+4
16W = 64
W = 64/16
W = 4cm
Hence the width of the rectangle is 4cm
Since l = 7w-
l = 7(4)-2
L = 28-2
L = 26cm
You can proceed and draw a rectangle with the dimension of 4cm by 26cm
Answer:
+1, -1, +11, -11
probably written with a +- symbol:
+-1, +-11
Maybe (silly) written like fractions:
+- 1/1, +- 11/1
Step-by-step explanation:
First list the factors of the leading coefficient. Here its 1. So we're going to use positive and negatives of the factors of 1, which is just +/- 1 . These numbers are going to go on the bottom of a fraction.
Next look for the factors of the constant, here it's 11
So that gives us
+/- 1, +/- 11 . These will go on the top of a fraction. (A fraction is a rational expression, that's why the name)
Then make all the combinations of
factors of constant
OVER
factors of leadingcoeff
So, we find
+/- 1, +/- 11
B). (-6,-7)

Answer:
Option A: -12x-8=10 is the correct answer.
Step-by-step explanation:
Given equation is:
-4 (3x+2) = 10
We will distribute the equation by multiplying the terms inside the brackets with -4.
Therefore,
-4*3x + 2*-4 = 10
-12x +(-8) = 10
-12x - 8 = 10
The equation -4 (3x+2) = 10 will become -12x-8=10 after distributing.
Hence,
Option A: -12x-8=10 is the correct answer.
