5x-2y 2.4what is the constant
Veronika [31]

For equation 5x - 2y = 2.4 the constant can be solve by converting the equation to a point slope form equation of a line. It is in the form y = mx + b

Dividing the whole equation by -2

<span>Y = 2.5x – 1.2 so the constant is 1.2</span>

Multiply (2x2 + 3x − 6)(x − 1)
Grace [21]
For this question, it is reasonable to use the foil method. In order to use FOIL we need to understand what it stands for: 
F-First
O-Outside
I-Inside
L-Last
(see attachment for visual) 
Let's get started. 
We are given: 
(2x^2 + 3x - 6)(x -  1)
Start by distributing the 2 first, then the 3, and then lastly the -6
<span><span><span><span><span><span><span>(<span>2x^2</span>)</span>(x)</span>+<span><span>(<span>2x^2</span>)</span><span>(−1)</span></span></span>+<span><span>(3x)</span>(x)</span></span>+<span><span>(3x)</span><span>(−1)</span></span></span>+<span><span>(−6)</span>(x)</span></span>+<span><span>(−6)</span><span>(−1)
From here multiply the terms you have gathered from FOILING: 
</span></span></span>2x^3-2x^2+3x^2-3x-6x+6

From here we combine like terms. Like terms are terms that contain the same variable and/or exponential value. For example: 
3c and 4c are like terms because they have the same variables 
24 and 50 are like terms because they are simply numbers without any variables.  
It is best to put the like terms together in parentheses so that it is easier to combine them. 
(2x^3)+(-2x^2+3x^2)+(-3x-6x)+(6)&#10;
Combine: 
2x^3+x^2-9x+6&#10;

Final answer: 2x^3+x^2-9x+6

antiseptic1488 [7]

Answer:

The two figures are similar and hey are not solid.

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

<em>Leah claims that these figures are not similar. When she compared the heights, she wrote 2/7. Then she compared the bases and 21/6. Why is Leah having trouble? Explain completely</em>

(Please have a look at the attached photo)

My answer:

In the first ratio, she compared the small figure's height to the large figure's height that is: 2/7

In the second ratio, she compared the large figure's base to the small figure's base that is: 21/6

=> She is wrong in this step, the ratio must be 6/21

Hence she needs to compare bases and heights thorugh division because the ratio between heights and the ratio between bases must be equal

\frac{21}{6}=3.5\\\frac{7}{2}=3.5

The scales are equal

=> Therefore, those rectangles are congruent.
