Answer:

13. 50+43=43+50

14. 5+(7+6)=(5+7)+6

15.  -15+0=0-15=-15

16.  \frac{3}{4}*\frac{4}{3}=1

17. 25*4=4*25

Step-by-step explanation:

Let "a", "b", and "c" real numbers.

- Commutative Property of Addition states that:

 a+b=b+a

- Associative Property of Addition states that:

(a+b)+c=a+(b+c)

- Additive Identity Property states that:

a+0=0+a=a 

- Commutative Property of Multiplication states that:

a*b=b*a

- Multiplicative Inverse Property states that:

a*\frac{1}{a}=1    (a\neq 0)

Knowing these properties, we can solve the exercise:

13. By the Commutative Property of Addition:

50+43=43+50

14. By the Associative Property of Addition:

5+(7+6)=(5+7)+6

15. By the Additive Identity Property:

-15+0=0-15=-15

16. By the Multiplicative Inverse Property:

\frac{3}{4}*\frac{4}{3}=1

17. By the Commutative Property of Multiplication:

25*4=4*25

Solve the problem 3g+7g+8=-10+g
Vinil7 [7]
First simplify like terms (things with the same letter):

3g + 7g + 8 = -10 + g

10g + 8 = -10 + g

Next we should take g off both sides:

9g + 8 = -10

Next isolate 9g by taking 8 off both sides:

9g = -18

Next divide both sides by 9 to find the value of g:

g = -2

Answer:

  • a) 2/3p
  • b) q + 1/2p

Step-by-step explanation:

<u>Given</u>

  • AB  = p
  • AD = q

a)

  • DC /AB = 3/2 ⇒
  • DC = 3/2AB = 3/2p

b)

  • BC = AD + (DC - AB)
  • BC = q + (3/2p - p) = q + 1/2p

What is the integral of a square root? Please explain.
IrinaK [193]
If y = xⁿ

∫y dx =  xⁿ⁺¹ / (n + 1)  +  C    Provided n ≠ -1.

y = √x

y = x^(0.5)

∫y dx  =  x^(0.5+1) / (0.5 + 1) =   x^(1.5)  / 1.5 = x^(1.5)  / (3/2)

∫y dx = (2/3) x^(1.5)  + C.

∫y dx = (2/3) x^(3/2)  + C.

∫y dx = (2/3)√x³  + C
