What is the difference of the solutions to (y-3)(y+3/2)=0?
I got stuck on the last part. Can someone answer this step by step please? And what is 3-3/2?
Answer:
(y-3)(y + 3/2) = 0
y = 3 or y = -3/2
the diff
3 - ( - 3/2 )
3 + 3/2
6/2 + 3/2
9/2 or 4.5

Answer:
The Scale Factor is 5.3
Step-by-step explanation:
Here's the reason why:
You are trying to make the rectangle much larger.
The 14yd by 6yd is trying to get to the 74.2yd by 31.8yd.
We need to remember the importance of length and width.
If 14 yards is our length then 74.2 yards is our length on the enlarged rectangle.
You must do 74.2/14 because we need to work backwords.
**You can't find something to multiply 14 by to get to 74.2 unless you do division.**
74.2/14 is 5.3
Now do the same with the width.
31.8/6
That is 5.3 as well.
Therefore the scale factor is 5.3
A triangle has side lengths of 6, 8, and 10. Is it a right triangle? Explain.
Answer:
yes
Step-by-step explanation:
Using the Pythagorean Theorem, considering that the sum of the squares of the lengths of the two smaller sides is equals to the square of the length of the greater side, the triangle is a right triangle.
Pythagorean Theorem:
The Pythagorean Theorem states that for a right triangle, the sum of the squares of the lengths of the two smaller sides is equals to the square of the length of the greater side.
so it is a right triangle.

Find the range of:
8, 14, 6, 12, 11,9
forgot can you explain the answer
Answer:
18 is 30% of 60
Step-by-step explanation:
Try to line up percents % and the actual numbers they represent.
number : precent
60 is 100%
18 is x %
cross multiply
x·60 = 100·18
divide both sides by 60 to isolate x
x = ((100·18)/60
x = 30
What is the area of this figure?
Use 3.14 for TT.
Please help
Answer:
406.08
Step-by-step explanation:
First FInd the area of the rectangle : which is short side * long side
-> 15*12=180m
Then find the area of the half circle, the formula of the area of a circle is [tex]\pi r^2[/tex]
here it's half a circle so it's [tex]\frac{\pi r^2}{2}[/tex] where r is 12
-> [tex]3.14\cdot \frac{\left(12\right)^2}{2}=226.08 m[/tex]
Finally just add the area of the rectangle with the area of the half circle
-> [tex]180+226.08=406.08 m[/tex]
What is the area of the following figure?
Answer:
A=31.5cm squared
Step-by-step explanation:
A=lw
A=(9)(3.5)
A=31.5
therefore A=31.5cm squared
Answer:
31.5 cm
Step-by-step explanation:
Just multiply the length and width
A. 197 cm
B. 158 cm
C. 155 cm
D. 55 cm
Answer:
158
Step-by-step explanation:
The Formula for Area is: A = L * W
First lets start with the rechtangle:
A = L * W
A = 17 * 7 = 119
the area of the rechtangle is 119
Now the triangle the formula is a little diffrent but it is the same concept
A=hbb (Picture below, it wont let me write it out right)
2=6·13
2=39
The area of the triangle is 39
Now add the both areas
119 + 39 =
158
Giovanni drops a rock from the Leaning Tower of Pisa in Italy. The height in feet (h) of the falling rock above the ground is
given by the following equation, where t represents the time, in seconds.
h = -16t2 + 186
Approximately how long will it take the rock to reach the ground?
It would take about 3.4 seconds for the rocks to reach the ground.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let h represent the height of the rock above the ground after t seconds. Given the equation:
h = -16t² + 186
The rock would reach the ground at h = 0, hence:
0 = -16t² + 186
16t² = 186
t = 3.4 seconds
It would take about 3.4 seconds for the rocks to reach the ground.

Volunteers from the Band Booster Club have already cleaned 2 rows of bleachers and will continue to clean at a rate of 7 rows per minute. The leadership class has completed 11 rows and will continue working at 4 rows per minute. Once the two groups get to the point where they have cleaned the same number of rows, they will take a break and decide how to split up the remaining work. How long will that take? How many minutes will each group have cleaned by then?

f(x) = 2(x - 1)(x + 4)
= 2(x^2 - x - 4x - 4)
= 2(x^2 - 5x - 4)
= 2x^2 - 10x - 8.
