72 ÷ 8 = 9
8 x 9 = 72
Sa bawat hanay, 9 na puno ang maitatanim.

Option C:

$\frac{3 a^{2} b^{11}}{2 }$ is equivalent to the given expression.

Solution:

Given expression:

$$\frac{-18 a^{-2} b^{5}}{-12 a^{-4} b^{-6}}$

To find which expression is equivalent to the given expression.

$$\frac{-18 a^{-2} b^{5}}{-12 a^{-4} b^{-6}}$

Using exponent rule: $\frac{1}{a^m}=a^{-m}, \ \ \frac{1}{a^{-m}}=a^{m}$

$$=\frac{-18 a^{-2} b^{5}a^{4} b^{6}}{-12 }$

$$=\frac{-18 a^{-2} a^{4} b^{5} b^{6}}{-12 }$

Using exponent rule: ${a^m}\cdot{a^n}=a^{m+n}$

$$=\frac{-18 a^{(-2+4)} b^{(5+6)}}{-12 }$

$$=\frac{-18 a^{2} b^{11}}{-12 }$

Divide both numerator and denominator by the common factor –6.

$$=\frac{3 a^{2} b^{11}}{2 }$

$$\frac{-18 a^{-2} b^{5}}{-12 a^{-4} b^{-6}}=\frac{3 a^{2} b^{11}}{2 }$

Therefore, $\frac{3 a^{2} b^{11}}{2 }$ is equivalent to the given expression.

Hence Option C is the correct answer.

2.2.2 checkup: practice problems

Answer:

1. 60 degrees

2. 50 degrees

4. 49 degrees

5. 26 degrees

Step-by-step explanation:

The sum of the measures of the angles of a triangle is 180 degrees.

x + 80 + 40 = 180

x + 120 = 180

x = 60

x + 75 + 55 = 180

x + 130 = 180

x = 50

x + 90 + 41 = 180

x + 131 = 180

x = 49

x + 81 + 73 = 180

x + 154 = 180

x = 26

Answer: x=-303

Step-by-step explanation:

x+310=7

We move all terms to the left:

x+310-(7)=0

We add all the numbers together, and all the variables

x+303=0

We move all terms containing x to the left, all other terms to the right

x=-303

Answer:

a&c

Step-by-step explanation:

because you can multiply to numbers and reach 0 or 2, but no number times another equals 7 and no number times 0 equals three (multiplicative identity of 0)
