Answer:
Step-by-step explanation:
Given,
Length (l) = 2(7z + 3) = 14z + 6
Breadth (b) = 5z
Now,
Perimeter of rectangle (P) = 2(l + b)
=2(14z + 6 + 5z)
=2(19z + 6)
=38z + 12
Answer:
x = 7
Step-by-step explanation:
A triangle's total interior angle measurement will equal 180°.
Set all measurements equal to 180:
(82) + (9x - 6) + (6x - 1) = 180
Simplify. Combine like terms:
(82 - 6 - 1) + (9x + 6x) = 180
(82 - 7) + (15x) = 180
(75) + 15x = 180
Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction

First, Subtract 75 from both sides of the equation:
15x + 75 = 180
15x + 75 (-75) = 180 (-75)
15x = 180 - 75
15x = 105
Next, divide 15 from both sides of the equation:
(15x)/15 = (105)/15
x = 105/15
x = 7
7 is your value for x.

The answer is -8/1 two negatives equals negative which would be -11 then subtract positive 3 equals-8
Answer:
the range of possible values for x are 1.6<x<9.6
Step-by-step explanation:
The answer is 5x^2y. The lowest exponent would be the GCF for each term if it has one
