Jayne says that 0.45 is equal to 4/10 is she correct? Explain

MissTica

No, it is not correct.

To compare this answer, do this.

$\frac{45}{100}$ is Jayne's 0.45 in fraction form.

If you simplify it you get $\frac{7}{20}$

$\frac{4}{10}$ ≠ $\frac{7}{20}$

How do I find the measure of angles

Thepotemich [5.8K]

Well you already know a whole circle is 360 and if there are any angles that already have there measurements you can use those and find the percent that isn’t accounted for is your angle......or just use a protractor

Answer:

c. $2a^3x^4-3a^3x^3+a^4x^2$

d. $63x^5y^3-30x^2y^4-7x^3y^2$

Step-by-step explanation:

For this exercise you need to remember the following:

1. The multiplication of signs:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-$

2. The Product of powers property, which states that:

$(a^m)(a^n)=a^{(m+n)}$

3. The Distributive property:

$a(b\±c)=ab\±ac$

Knowing that, you can solve the multiplication of the polynomials:

c. $(-2ax^2+3ax-a^2)(-a^2x^2)=\\\\=(-2ax^2)(-a^2x^2)+(3ax)(-a^2x^2)+(-a^2)(-a^2x^2)=2a^3x^4-3a^3x^3+a^4x^2$

d. $(6.3x^3y-3y^2-0.7x)(10x^2y^2)=\\\\=(6.3x^3y)(10x^2y^2)+(-3y^2)(10x^2y^2)+(-0.7x)(10x^2y^2)=63x^5y^3-30x^2y^4-7x^3y^2$
