Answer:

c. 14q²-2q+14/3

Step-by-step explanation:

9q²-2/3(3q-7)+5q²

multiply 2/3 with bracket

= 9q²-2q+14/3+5q²

=14q²-2q+14/3

Answer:

C

Step-by-step explanation:

Given

9q² - \frac{2}{3}(3q - 7) + 5q² ← distribute parenthesis by - \frac{2}{3}

= 9q² - 2q + \frac{14}{3} + 5q² ← collect like terms

= 14q² - 2q + \frac{14}{3} → C

The area of a parallelogram is given by the formula A=bh the area of the parallelogram on the right is 126 sq units. Find its ba
Elden [556K]
From the diagram we have

Base = 4x+1
Height = x+1

Area = Base × Height
126 = (4x+1)(x+1) ⇒ Expand the double bracket
126 = 4x^{2}+5x+1 ⇒ Subtract 126 both sides
0 = 4x^{2}+5x-125 ⇒ Factorise the quadratic expression
0 = (x-5)(4x+25) ⇒ Equating each factor to zero

x-5=0                       4x+25=0
x=5                           x=- \frac{25}{4}

We need the positive value of x so we use x=5

Height = 5+1 = 6
Base = 4(5)+1 = 21

Help Please I'm Out Of Time ;(
Dafna11 [192]

Answer:

Not true.

Step-by-step explanation:

Whole numbers are integers that are 0 or greater than 0.  Since 0 is a whole number and x > 0 does not include 0, the statement is not true. Only the sign ≥ includes 0.

Jack has written the name of each planet of the solar system on a separate piece of paper and has placed all these pieces of pap
Alinara [238K]

Answer:

<em>The probability that it would contain at least 6 letters is: </em><u><em>5/8</em></u>

<u><em></em></u>

Step-by-step explanation:

From the question given above,

We know that there are 8 planet that was given.

Mercury        7 letters

Venus           5 letters

Earth             5 letters

Mars              4 letters

Jupiter            7 letters

Saturn             6 letters

Uranus             6 letters

Neptune.          7 letters

Therefore,

P(at least 6 letters) + P( Less than 6 letters) = 1

P (at least 6 letters) + P (3 planet) = 1

P (at least 6 letters) +  ( 3/8) = 1

P(at least 6 letters) = 1 - (3/8)

= 5/8

Graph the following and determine in which quadrants the graphs lie: y= 1/3x
natta225 [31]

y = 1/3x

The slope is 1/3 ( the slope is the number with the variable x).


There is no other operation ( addition or subtraction) so the y- intercept is 0

The first point of the graph would be (0,0)


Calculate another point , lets use x = 3

y = 1/3(3) = 1

The second point is (3,1)


The line of the graph is an angled line which is located in quadrant 1 and 3.
