Looks like you meant to write (p/q)³ if so it's power of a quotient

Micaela is 2 years older than Sam. In 4 years, the sum of their ages will be 40. How old is Micaela now? Describe and fix any er

Verdich [7]

Answer:

Micaela is 17

Step-by-step explanation:

s+2=m

(s+2+4)+(s+4)=40

(s+6)+(s+4)=40

2s+10=40

40-10=30

2s=30

30/2= 15

s=15

{s+2=m}

15+2=m

m=17

I need the surface area of this shape EASY POINTS Explain your answer

Alexus [3.1K]

Hi there! :)

So, to find the surface area, all you need to do is find the area of each surface on the shape.

Theres 5 different shapes in the model, so you're going to need to find the area of each one.

There is:

1. left side triangle

2.right side triangle

3.slanted rectangle

4.bottom rectangle

5. back rectangle

all the rectangles are simple, so let's start with them.

the dimensions of the slanted rectangle are 7m and 8m, so 8•7 is 56.

the dimensions of the bottom rectangle are 5m and 7m, so its 35.

the back rectangle has 5m and 7m so it is 35.

Halfway done!!

Now, onto the triangles. they're the same thing as the rectangles, but you half to 'cut it in half' or just divide by two. both of the triangles will be the same.

the triangles measurements are 5m and 8m, so 5•8 is 40, 40÷2 is 20. both of the triangles being 20, now all we have to do is add it up.

20+20+35+35+56=166

and that's about it!

I hope this helps, sorry it took so long to answer, but I hope you have a good day!

22. Mona is in her garden jumping on stones (as shown below).

iris [78.8K]

$\large\green{\sf\boxed{Given:-}}$

Mona starts from 68th stone

She jumps 23 stones ahead 

Then she jumps 28 stones back

$\large\red{\sf\boxed{To \:find:-}}$

Her final position=?

$\large{|\underline{\mathtt{\red{S}\blue{o}\orange{l}\pink{u}\blue{t}\purple{i}\green{o}\red{n}\blue{:}\orange{-}}}}$

Add 23 in 68 [Given]

$\begin{gathered}\\ \sf\longmapsto 68+23=91\end{gathered}$

Subtract 28 from 91

$\begin{gathered}\\ \sf\longmapsto 91-28=Her\:final\:position\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto =63\end{gathered}$

To find how much stones she is ahead or back we will Subtract 63 from 68 which was her initial position.

$\begin{gathered}\\ \sf\longmapsto 68-63=5\end{gathered}$

So, Mona will be 5 stones behind from the starting stone.

☯️Hence, Option C is correct

Let f(x)=2x^2+7x-5 and g(x)=-8x^2-3x+5 what is g(x)+f(x)

ser-zykov [4K]

F(x) = 2x² + 7x - 5
g(x) = -8x² - 3x + 5
g(x) + f(x) = -8x² - 3x + 5 + 2x² + 7x - 5 = - 6x² + 4x

Answer: -6x² + 4x
