An expression is shown below.
6ab^2 + 9a^2b
Which of the following shows an equivalent expression?
Answers
Answer:
C. 3ab ( 2b + 3a )
Step-by-step explanation:
substitution
Hi! I'm happy to help!
To first solve this, Let's see if we can simplify our expressions using the order of operations: our original expression cannot be simplified. The first expression cannot be simplified. The second expression we can multiply the outside by the parenthesis by the inside, same with the third and fourth.
(make sure everything outside of the parenthesis is being multiplied by each part inside of the parenthesis)
9a²b²
9a²b²
3ab(3b+2a)
ab(9b+6a)
b(9ab+6a²)
9ab²+6a²b
3ab(2b+3a)
ab(6b+9a)
b(6ab+9a²)
6ab²+9a²b
3a²b²(2b+3a)
a²b²(6b+9a)
b²(6a²b+9a³)
6a²b³+9a³b²
Now that we have all expressions fully simplified, let's compare to see which one matches.
Our first expression is nowhere close to what our original expression is, 1 is incorrect.
Our second expression is close, but it has the 9 and the 6 flipped, even if we rearrange the expression like this, 6a²b+9ab², it still doesn't match, so 2 is also incorrect.
Our third expression has the correct numbers, variables, placement, and exponents, so 3 is correct.
Our fourth expression has incorrect exponents, the expression made every variable multiplied by ab an extra time, so 4 is incorrect.
In summary, you should pick number 3, because it is equivalent.
I hope this was helpful, keep learning! :D

The double bar graph shows how long, on average, different
animals live both in the wild and in captivity.
Which animal's life span in captivity has the least difference from
its life span in the wild?
ears
Answers
Answer: Cheetah
Step-by-step explanation: I got it right on the test :)
The animal with the least difference is cheetah with a value of 5
From the double bar chart attached :
Life span in wild is = blue bar
Life span in wild is = blue bar Life span in captivity = brown bar
Calculating the approximate difference between the two bar values as obtained from the graph :
CHEETAH = 17 - 12 = 5
POLAR = 35 - 20 = 15
TIGER = 26 - 20 = 6
GIANT PANDA = 30 - 20 = 10
LEOPARD = 28 - 20
The animal with the least difference between it's span in the wild and in captivity is CHEETAH with a value of 5.

Step-by-step explanation:
The difference between their weights can be found by subtracting 6 1/4 pounds from 5 9/16 pounds to find the difference. To do this we must transfer it from 1/4 to sixteenths which is 4 sixteenths. Then we subtract.

Type the correct answer in each box. A circle is centered at the point (-3, 2) and passes through the point (1, 5). The radius of the circle is units. The point (-7, ) lies on this circle.
Answers
Answer:
The circle has like an equation: (x+3)²+(y-2)²=r²
If x=1 then y=5 ==>(1+3)²+(5-2)²=r²==>4²+3²=r²==>r=5 (the radius)
if x=-7 then (-7+3)²+(y-2)²=25 ==> (y-2)²=25-16==>y=2+3 or y=2-3
The points (-7,5) and (-7,-1) are on the circle.

Answer:
Step-by-step explanation:
The slope or, gradient is the rate of change of a linear function( a function which can be represented by a line). We find a slope between two arbitrary pair of points( arbitrary means what the question given us). One point we are given is (0,4) and an another point we are given is (2,1). Now we use the slope formula,
[tex]\frac{change in y }{change in x}[/tex]
So let plug in the values,
[tex]\frac{4-1}{0-2} =\frac{3}{-2} =-\frac{3}{2}[/tex]
The slope is -3/2

Vertex is (-8, 4) not one of the answers offered!
Step-by-step explanation:
Factor -1/8 out of the first two terms. Leave a space inside parentheses in which to add a number.
[tex]y=-\frac{1}{8}(x^2 + 16x + \text{-----})-4[/tex]
Complete the square by squaring half the coefficient of x and adding it in the space.
[tex](\frac{16}{2})^2=64[/tex]
Add 64 in the space you made, then compensate for that at the end of the expression by subtracting [tex]-\frac{1}{8}(64)=-8[/tex]
[tex]y=-\frac{1}{8}(x^2+16x+64)-4+8\\y=-\frac{1}{8}(x+8)^2+4[/tex]
The x-coordinate of the vertex is the opposite of +8, the number inside the parentheses. The y-coordinate of the vertex is the number at the end of the expression.

Step-by-step explanation:
Explanation:
Sin(theta) = opp/hyp => hyp = opp/sin(theta)
Find opp:
opp = sqrt(6^2 + 6^2)
= sqrt(72)
= 6sqrt(2)
= 6 x 1.41
Hyp(also is x) = (6 x 1.41)/Sin(60°)
= (6 x 1.41 )/0.86
= 9.83
= 10 (round up)
And 4sqrt(6) = 9.79 = 10 (round up)
Thus I concluded that x = 4sqrt(6)
