Simplify:
√3 (√3+x)
A. (3+x)√3
B. 2x√3
C. 3+x√3
(I'll mark brainliest if you explain and show your work)
Answer:
C
Step-by-step explanation:
[tex]\sqrt{3}[/tex] times [tex]\sqrt{3}[/tex] = 3 and [tex]\sqrt{3}[/tex] times x = [tex]\sqrt{3}[/tex]x
So that means that answer is 3+[tex]\sqrt{3}[/tex]x which is C

The trend line passes through (10,9) and (35,0). Write an equation for the trend line.
Answer: Solution :
Step 1 :
Make a scatter plot of Lily’s running data.
Step 2 :
To draw a trend line, use a straight edge to draw a line that has about the same number of points above and below it. Ignore any outliers.
Step 3 :
Find the slope of the trend line.
The line passes through points (2, 20) and (4.5, 45).
Use the slope formula.
m = (y2 - y1) / (x2 - x1)
Substitute x1, = 2, y1 = 20, x2 = 4, and y2 = 45.
m = (45 - 20) / (4.5 - 2)
m = 25 / 2.5
m = 10
Step 4 :
Find the y-intercept of the trend line.
Slope-intercept form equation of a line :
y = mx + b
Plug y = 20, m = 10 and x = 2.
20 = 10 · 2 + b
20 = 20 + b
Subtract 20 from both sides.
0 = b
Step 5 :
Use your slope and y-intercept values to write the equation.
Slope-intercept form equation of a line :
y = 10x + 0
So, the equation for the trend line is
y = 10x

3(4x+5) = 12x+15 what does it equal?
Answer: AllRealNumbers
Step-by-step explanation:
1. Distrubute: 3(4x+5)=> 12x+15
2. Simplify: 12x+15=12x+15
=> 15=15
Since it cancels out it means that x can be any real number.

Im struggling in math rn and i need help with this problem 3 1/4 = 1/2 + w
Answer:
w= 2 3/4
Step-by-step explanation:
First, we need to find what can equal w. So, we can subtract 1/2 form both sides, so one sides has just w and one side has just a number. 3 1/4-1/2= 2 3/4. So w= 2 3/4
Answer:
2 3/4
Step-by-step explanation:
3 1/4 = 1/2 + w
Transfer 1/2 to other side
3 1/4 - 1/2 = w
Solve
w = 2 3/4

Ben sells homemade cards at a craft fair. He wants to earn more than $50 at the fair. He sells his cards for $2 and he has already earned $36. How many cards foes he need to sell to reach his goal? Write and solve an inequality.
Answer:
He must sell 8 cards to reach the minimum goal.
Step-by-step explanation:
Giving the following information:
He wants to earn more than $50 at the fair.
He sells his cards for $2 and he has already earned $36.
First, we need to calculate the money required to reach the minimum goal:
51 - 36= $15
Now, we write the inequality:
2*x >15
x= number of cards sold.
x>15/2
x> 7.5
He must sell 8 cards to reach the minimum goal.

Price: $8.62 per 3 lb of strawberry
How much will it cost to buy 4.2 lb of strawberries? (Round to 2 decimal digits if necessary)
9514 1404 393
Answer:
$12.07
Step-by-step explanation:
The cost is proportional to the weight, so we have ...
dollars/pounds = c/4.2 = 8.62/3
Multiplying by 4.2 gives ...
c = 4.2×8.62/3 = 12.068
The cost of 4.2 pounds of strawberries is $12.07.
Please help, and plz don't be saying this is the right answer if u dont know for sure.
Answer:
The blank in the equation is 1.
x = 7 and the vertical angles measure out to 64 degrees.
Step-by-step explanation:
When solving for x, you always want to keep the variables on one side. So you'll subtract 9x from both sides. That gives you 1=3x-20. Then you'll add 20 to both sides. This gives you 21=3x. After you'll divide by 3 on both sides. This gives you 7=x.
Now you'll plug in 7 for x. This gives you 12*7-20=9*7+1. First, you'll multiply which gives you 84-20=63+1. Add and you'll get 64 on both sides.
