C. 5r (r + 4
Answer:
A) 6Gn + 12 (or 6n+12, if that’s what you meant)
B) 4p²+9p
C) 5r²+20r
Step-by-step explanation:
A. If you meant 6(n+2)...
Multiply 6 by n and also 6 by 2:
6n + 12
B. Multiply p by 4p and also p by 9
4p²+9p
C. Multiply 5r by r and also 5r by 4
5r²+20r

a) Complete the table of values for y = x2 + x - 4
х
-3
-2
-1

y
Answer:
The values of y for each value of x are:
[tex]x = -3, y =2[/tex]
[tex]x = -2\: , y =-2[/tex]
[tex]x = -1\: , y =-4[/tex].
[tex]x = 0\: , y =-4[/tex]
[tex]x = 1\: , y = -2[/tex].
[tex]x = 2\: , y =2[/tex]
[tex]x = 3\: , y = 8[/tex]
Step-by-step explanation:
We have all the values of x, they are from -3 to 3 passing for 0.
Now, we know that y is a quadratic function (y=x²+x+4)
Therefore, we just need to put each value of x into the quadratic equation to find each y value.
When:
[tex]x = -3, y = (-3)^2+(-3)-4=2[/tex]
[tex]x = -3\: , y = 2[/tex]
We can do this for all values of x, so we will have:
[tex]x = -2\: , y = (-2)^2+(-2)-4=-2[/tex]
[tex]x = -1\: , y = (-1)^2+(-1)-4=-4[/tex].
[tex]x = 0\: , y = (0)^2+(0)-4=-4[/tex]
[tex]x = 1\: , y = (1)^2+(1)-4=-2[/tex].
[tex]x = 2\: , y = (2)^2+(2)-4=2[/tex]
[tex]x = 3\: , y = (3)^2+(3)-4=8[/tex]

The two trapezoids below are similar. What is the length of EF?
Answer:
x/24 = 7.5/30
30x = 180
________
30
x= 6
The length of EF in given trapezoid is 6 cm
What is trapezoids ?Trapezoids are quadrilaterals that have two parallel sides and two non-parallel sides. It is also called a Trapezium. A trapezoid is a four-sided closed shape.
a pair of opposite sides are parallel.
diagonals of trapezium bisect each other.
sum of all four angles of trapezium is = 360°
it has four unequal sides.
diagonals are congruent.
opposite side of an isosceles trapezium are congruent.
According to the question
Trapezoids ABCD and EFGH are similar,
Hence, corresponding sides ratio are equal
Thus, AB/EF = DC/HG
24/x = 30/7.5
30x = 180
x = 180/30
x= 6
Hence, The length of EF is 6 cm

15 - 3x = 11 - 3x + 4
Answer:
Infinitely Many Solutions!
Steps I used to get the answer :
1. Cancel -3x−3x on both sides.
15=11+4
2. Simplify 11+4 to 15.
15=15
3. Since both sides equal, there are infinitely many solutions.
Infinitely Many Solutions!
Done by NeighborhoodDealer.
Answer:
Step-by-step explanation:
Solve for x:
15 - 3x = 11 - 3x + 4
Subtract 4 from both sides
15 - 3x - 4 = 11 - 3x + 4 - 4
11 - 3x = 11 - 3x
This equation has infinite solutions since both sides of the equation are equal.

Emily works at a perfumery. She extracts 3 liters of essential oil for perfumes in 2 days.
Assuming Emily extracts essential oil at a constant rate, we can graph this relationship with time in days along the x-axis and quantity of oil in liters along the y-axis. The slope of the line representing this relationship is
.
A point on this line that corresponds to the amount of oil Emily extracts after 5 days is (5,

what fraction is greater than 1/5 and less than 1/3
The fraction 1/4 is greater than 1/5 and less than 1/3
What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction that can be written as the form of p : q, which is equivalent to p / q.
We need to find the fraction that is greater than 1/5 and less than 1/3
Since we know that 1/5 < 1/4 < 1/3
When the numerator is less than the denominator, the fraction is called proper fraction, otherwise it is called improper fraction that proper fraction is also called fraction which is less than 1.
Therefore the answer is; 1/4
