If x and y are both negative when is x-y positive

1 answer:

7 0

X-y is positive when y is further away from 0, compared to x. In other words, when y is a larger negative

For example
x = -2
y = -5

x-y = -2-(-5) = -2+5 = 3

What is the total surface area

Stels [109]

We have two right triangles and three different rectangles.

The formula of an area of a right triangle:

$A_T=\dfrac{1}{2}l_1l_2$

l₁, l₂ - legs

We have l₁ = 20cm and l₂ = 21cm. Substitute:

$A_T=\dfrac{1}{2}(20)(21)=(10)(21)=210\ cm^2$

The formula of an area of a rectangle:

$A_R=lw$

l - length

w - width

We have:

rectangle #1: l = 22cm, w = 29cm

$A_{R1}=(22)(29)=638\ cm^2$

rectangle #2: l = 22cm, w = 21cm

$A_{R2}=(22)(21)=462\ cm^2$

rectangle #3: l = 22cm, w = 20cm

$A_{R3}=(22)(20)=440\ cm^2$

The total Surface Area of the triangular prism:

$S.A.=2A_T+A_{R1}+A_{R2}+A_{R3}\\\\S.A.=2\cdot210+638+462+440=1960\ cm^2$

The number 1953125 is equal to 5^9. Explain how the information above tells you that it is not a square number. I've tried the a

ddd [48]

Answer:

$5^{9}$ can not be expressed as a square of any other number.

Step-by-step explanation:

The number 1953125 is equal to $5^{9}$ .

Now, the above statement gives an idea that 1953125 i.e. $5^{9}$ is not a square number as 9 is not a multiple of 2.

So, we can not express $5^{9}$ as a square of any other number.

We can only express $5^{9}$ as $(5^{4} )^{2} \times 5$ .
