Answer:

135

Step-by-step explanation:

You can you the word pemdas to help you. P : parentheses

E: exponents

M: Multiplication

D: division

A: addition

S: subtraction.

But for the distributive property to work, we would have to separate the 4 & 9, so the equation would look like this =

9 x (4) + 9 x (9) =

36 + 81 =

117

Hope that helps!

Answer:

Width = 2x²

Length = 10

Step-by-step explanation:

The greatest common monomial factor of 14x² and 6x² is 2x² so the width is 2x².

Width = 2x²

Length = (14x² ÷ 2x²) + (6x² ÷ 2x²)

= 7 + 3

= 10

Line b passes through the Point(-3, -4) and has a slope of -1/2. What is the equation of Line b in standard form?

Anna11 [10]

Answer:

$x+2y=-11$

Step-by-step explanation:

Slope intercept form of a line is given by:

$y=mx+b$

Where

m is the slope and b is the y-intercept

Given slope is $-\frac{1}{2}$

We can write:

$y=-\frac{1}{2}x+b$

Now to find b, we replace x with -3 and y with -4, given, so we have:

$y=-\frac{1}{2}x+b\\-4=-\frac{1}{2}(-3)+b\\-4=\frac{3}{2}+b\\b=-5.5$

So, the equation is:

$y=-\frac{1}{2}x-\frac{11}{2}$

Now,

The standard form is given by:

$Ax+By=C$

So, we take x and y to left side and the constant to right side. Rearranging, we get:

$y=-\frac{1}{2}x-\frac{11}{2}\\2y=-x-11\\x+2y=-11$

The first answer choice is right.
