Answer:

a) -8yx-20y

b) -6x ² - 3xy - 16x -2y - 8

Step-by-step explanation:

a) -4y(2x+5) apply multiplicative distribution law

-4y × 2x - 4y × 5 multiply the monomials

-8yx - 20y

b) kinda the same steps like a

:) distributive property btw

hope it helps if you need the steps for b I'll send them in the comment

Complete the missing value in the solution to the equation.<br> y=-2x+4<br> y=-2

anygoal [31]

Answer:

X=3,y=-2

Step-by-step explanation:

This is a simultaneous equation question and we will have to solve using substitution method

So let's solve

y=-2x+4...(1)

y=-2....(2)

Let's substitute (2) into (1)

-2=-2x+4

Substrate 4 from both sides

-6=-2x

Divide both sides by-2

x=3

Substitute the value of x in (1)

y=-2(3)+4

y=-6+4

y=-2

Therefore x is 3,y is -2

the area of a window is 40 square feet. the length is the square root of 20 feet. what is the width of the window

Irina18 [472]

----------------------------------------------------
Given information
----------------------------------------------------
Area = 40ft²
Length = √20 ft

----------------------------------------------------
Formula
----------------------------------------------------
Area = Length x Width

----------------------------------------------------
Find Width
----------------------------------------------------
40 = √20 x width
Width = 40 ÷ √20
Width = 40 ÷ 2√5
Width = 20 ÷ √5
$Width = \frac{20}{ \sqrt{5} }$

$Answer: \boxed {Width = \frac{20}{ \sqrt{5} }}$

Can transformations always be applied to shapes, even if they're not in a plane?

Tatiana [17]

A translation is a transformation of the plane in which a a plane figure slides along a straight line, and changes its position without turning. Each point moves the same distance and in the same direction. Hence all points subjected to the same translation undergo the same displacement.

What is a 3, 4, 5 triangle?

Alexandra [31]

Answer:

<em>A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an "angle-based" right triangle.</em>

Step-by-step explanation:

Hope this helps
