Answer:

P = 25

Q = 133

R = 22

Step-by-step explanation:

x + 13 + 10x + 13 + 2x - 2 = 180 add x's

13x + 13 + 13 - 2 = 180 add number's on left

13x + 24 = 180 subtract 24 from both sides

13x = 156 divide both sides by 13

x = 12

x + 13 = 12 + 13 = 25

10x + 13= 10(12) + 13 = 133

2x -2 = 2(12) - 2 = 22

Answer:

B. 1

Step-by-step explanation:

Multiply the first term by $x^a$ , the second term by $x^b$ , the third term by $x^c$ .

<u>The first term becomes:</u>

$x^a/(x^a+x^b+x^c)$

<u>The second term becomes:</u>

$x^b/(x^a+x^b+x^c)$

<u>The third term becomes:</u>

$x^c/(x^a+x^b+x^c)$

<u>Their sum is:</u>

$(x^a+x^b+x^c)/(x^a+x^b+x^c) = 1$

Correct choice is B

What is the volume of this square pyramid?

tatuchka [14]

Answer: 1296 cm³

Step-by-step explanation:

Since, the volume of a square pyramid is,

$V = \frac{a^2h}{3}$

Where a = side of the square base,

h = height of the pyramid,

By the given diagram,

a = 18 cm,

h = 12 cm,

Hence, the volume of the given pyramid,

$V = \frac{18^2\times 12}{3}$

$= \frac{324\times 12}{3}$

$=\frac{3888}{3}$

$=1296$ cube cm.

⇒ First option is correct.
