13(12x+15)=7
156x+195=7
156x=7-195
156x=-188
156x/156x=-188/156
x=1.20512820513
Answer:
<h2>652 ft²</h2>
Step-by-step explanation:
Look at the picture.
It's a net of right rectangular prism.
We have three pairs of rectangles:
7ft × 8ft
7ft × 18ft
8ft × 18ft
The formula of an area of a rectangle l × w:
A = lw
Calculate the areas:
A₁ = (7)(8) = 56 ft²
A₂ = (7)(18) = 126 ft²
A₃ = (8)(18) = 144 ft²
The Surface Area :
S.A. = 2A₁ + 2A₂ + 2A₃
Substitute:
S.A. = 2(56) + 2(126) + 2(144) = 652 ft²
The function rule for the equation y = -5x - 1 is
(x,y) ⇒ (0,-1) , (-1,4) , (3,-16)
<h3>What is dependent variable and independent variable ?</h3>
In a mathematical equation independent variable is set by us to examine the give equation or function how it is behaving or it's value for a specific value being set by us.We can also think of independent variable as the input to a function and dependent variable as the output.
According to the given question
y = -5x -1 the table is illustrated below
x -2 -1 0 1 2 3
y 9 4 -1 -6 -11 -16

I see two ways to do it.
First, you have to understand that when you see a 'complex fraction' like this, the top number is a numerator, and the two bottom numbers are both denominators.
Way-1:
Take the top fraction . . . 2/2 . That's equal to 1 . So the whole thing is <em>1/3</em>.
Way-2:
Multiply the bottom two denominators. Then the whole thing is 2/(2·3) . That's the same thing as 2/6 . Simplify that, and you have <em>1/3</em> .
