Oduvanchick [21]3 years ago
8 0

Answer:

22)

  • 2(length+breadth+h)
  • 2(5a^2b^2+3ab^2)
  • Perimeter: 2ab^2(5a^2+31)

Area:-

  • 5a^2b^4 *3ab^2
  • A=15a^2b^6

-----------

23)

perimeter:-

  • 4m^2+3mn^2+7mn
  • 4m^2+10mn^2
  • answer: 2m(2m+5n^2)

Area:-

  • \frac{1}{2}* base* height
  • 1/2*3mn^2*4m^2
  • 6mx^{2+1}n^2
  • A=6m^3n^2

----------

24)

  • 1/2*b*h
  • 1/2x^24m^2*8mn
  • A=16m^3n

----------

25)

  • 1/2*(7a^2b+11a^2b)*3ab
  • 1/2*18a^2b*3ab
  • 9a^2b*3ab
  • A=27 a^3b^2

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

26)

  • A= 9\pi (x^3y)^2

∴To calculate the perimeter , add the length of its sides.

∴To calculate the area, multiply its height by its width.

<u>------------------------</u>

hope it helps...

have a great day!!

Solve:-<br><br> 7^5<br><br> Thanks!!!!!!!!!!!!!
solong [7]
These are exponents. To solve an exponent you need to multiply the base it self how many times its says in the power.

a² 

a = base
<span>2 = power
</span>
7^5 = 7 × 7 × 7 × 7 × 7 = <span>16807
7^5 = </span><span>16807</span>

Sonbull [250]

Answer:

V =  \frac{4}{3} \pi {r}^{3}  \\  \\ 3V = 4\pi {r}^{3}  \\  {r}^{3}  =  \frac{3V}{4\pi}  \\  \\ r =  \sqrt[3]{ \frac{3V}{4\pi} }
