Determine which of the following terms are not considered to be like terms with the expression -6s ( the two is squared like on

Iteru [2.4K]

Answer:

$s^2t^2$

$4(s\cdot t)$

$-6(s^2+t)$

Step-by-step explanation:

We want to select all the terms that are not considered to be like terms with $-6s^2t$ .

The terms that are like terms with $-6s^2t$ must have $s^2t$ .

It doesn't matter the coefficient.

So we can easily see that all the following are not like terms with $-6s^2t$ :

$s^2t^2$

$4(s\cdot t)$

$-6(s^2+t)$

The height of a pyramid is doubled, but its length and width are cut in half. What is true about the volume of the new pyramid?

Aleksandr [31]

Answer:

The new pyramid has a volume that is half the volume of the original pyramid.

Step-by-step explanation:

The volume of a pyramid is given by the following equation:

$V = \frac{h*l*w}{3}$

In which h is the height, l is the length and w is the width.

Modified volume:

height doubled, length and width cut in half. So

$h = 2h, l = 0.5l, w = 0.5w$

$V_{M} = \frac{2h*0.5l*0.5l}{3} = \frac{0.5*h*l*w}{3} = 0.5\frac{h*l*w}{3}$ = 0.5V[/tex]

That is

The new pyramid has a volume that is half the volume of the original pyramid.

the height of a tree was 8 feet. after a year, tree's height increased by 25%. use a bar diagram to find the new height of the t

marysya [2.9K]

8×.25=2
8-2=6
so what you would do is make a bar graph where the y axis would be years and the x axis being height

3х – 8y = 34<br> 7х + 4у = -34<br> Solve by elimination <br> Y and x<br> Please show steps ):

garri49 [273]

Answer:

The answer would be (-2, -5)

Step-by-step explanation:

3x - 8y= 34

2(7x + 4y = -34)

3x - 8y=34

14x + 8y= -68

----------------------

17x= -34 divided by 17

x = -2

3(-2) -8y= 34

-6 -8y =34 add 6

-8y= 40 divide by -8

y = -5

if you want to check the answer replacing -2 for x and -5 for y

7(-2) + 4(-5)= -34

-14 + (-20) = -34

-34 = -34

I hope this help sorry I'm not good explaining
