Evaluate using properties of arithmetic operations. 12∙121∙13÷(26∙11)∙7÷11

Anika [276]

Answer:

0.1978

Step-by-step explanation:

According to the rule of BODMAS (or FEDMAS), let us do the bracket first.

26·11 = 286

Now, do the multiplication from the left.

12·121·3 = 4356

286·7 = 2002

Now, do the division from the left.

$\frac{\frac{4356}{2002} }{11}$

$=\frac{4356}{2002(11)}$

$=\frac{396}{2002}$

= 0.1978

What is the measurement of angle a?

Illusion [34]

Assuming we have parallel lines, we can solve for x.
Since a = 3x - 10 (vertically opposite angles are equal),
3x - 10 = 2x + 15 (alternate angles are equal)
x = 25

Hence, angle a = 3(25) - 10 = 65°

How do I solve this?

Artemon [7]

a^2 - b^2 = (a + b)(a - b)

In this case

49x^4y^2 - 4z^2

= (7x^2y)^2 - (2z)^2

= (7x^2y + 2z)(7x^2y - 2z)

Factors are (7x^2y + 2z) and (7x^2y - 2z)

Answer:

D) 7x^2y + 2z
