what is the common difference in the sequence (-3, 2, 7, 12, ...)
Answer:
an=a1+d(n−1) a n = a 1 + d ( n - 1 )
Step-by-step explanation:
This is an arithmetic sequence since there is a common difference between each term. In this case, adding −5 to the previous term in the sequence gives the next term. In other words, an=a1+d(n−1) a n = a 1 + d ( n - 1 ) .

Answer:
3x-5=3
Step-by-step explanation:
Answer:
2.6 repeating Or 8/3(same thing in fraction form)
Step-by-step explanation:
So, lets iscolate the different parts of this euqation:
Five less than 3 times a number is 3
Or:
5 less than 3 * x = 3
This is a bit tricky here, but it should be:
(3*x)-5=3
Since order of operations, multipcation comes first.
And remember this is 5 less than the 3*x, so its subtracting 5 from 3*x.
This is all equal to 3.
Now lets solve:
(3*x)-5=3
Solve whats in the parthese first:
3x-5=3
Then get 3x alone:
3x=8
Then get x alone:
x=8/3
Or
2.66 repeating
This is your answer(8/3 or 2.6)
Hope this helps!
m∠1=(3x+21)° and m∠3=(4x+9)° what is the value of x
Value of [tex]x[/tex] as per considering given pair as vertical opposite angles is equals to [tex]12[/tex] degrees.
What are vertical opposite angles?" Vertical opposite angles are defined as when two straight line intersect each other , the two non adjacent angles are vertical opposite angles. Measure of vertical opposite angles are always equal."
According to the question,
Given measure of angles,
[tex]m \angle1 = (3x + 21)\°[/tex]
[tex]m \angle3= (4x + 9)\°[/tex]
Consider both the angles as vertically opposite angles we get,
[tex]m \angle1 =m \angle3 \\\implies(3x + 21)\° = (4x + 9)\°\\\\\implies 4x -3x = (21 - 9))\°\\\\\implies x = 12\°[/tex]
Hence, value of [tex]x[/tex] as per considering given pair as vertical opposite angles is equals to [tex]12[/tex] degrees.

C)
Yes; SSS; ΔTSU ∼ ΔXWV
D)
The triangles aren't similar.
Answer:
Yes (SSS) Triangle SUT is congruent to triangle XWV
Step-by-step explanation:
15/10 = 1.5
9/6 = 1.5
12/8 = 1.5
In ΔSUT and ΔXWV the given sides are in proportion. Therefore, option A is the correct answer.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
The given two triangles are ΔSUT and ΔXWV.
From the triangle SUT, SU=10, UT=8 and ST=6
From the triangle XWV, VW=12, XW=15 and VX=9
Now, SU/XW = UT/VW = ST/VX
10/15 = 8/12 = 6/9
2/3 = 2/3 = 2/3
The given sides are in proportion.

using the zero product property.
Answer:
The answer is (x + 3) (x - 7) = 0
Step-by-step explanation:
x² - 4x = 21
x² - 4x - 21 = 0
x² - 7x + 3x - 21 = 0
x(x - 7) + 3(x - 7) = 0
(x + 3) (x - 7) = 0

A circle is placed in a square with a side length of 10 mm, as shown below. Find the area of the shaded region.
Use the value 3.14 for it, and do not round your answer. Be sure to include the correct unit in your answer.
Answer:
21.5
Step-by-step explanation:
The area of the shaded region is 21.5 mm².
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
Given is a circle inside a square.
Area of a square = a², where 'a' is the side length.
Here, a = 10 mm
Area of square = 10² = 100 mm²
Area of a circle = π r², where r is the radius of the circle.
Diameter of circle = 10 mm
Radius of the circle = 10/2 = 5 mm
Area of the circle = (3.14) (5²) = 78.5 mm²
Area of the shaded region = Area of square - Area of circle
= 100 mm² - 78.5 mm²
= 21.5 mm²
Hence the area is 21.5 mm².

What is the lowest whole number for hypotenuse c when using the formula [tex]\sqrt{a^2+b^2}[/tex] and a = b?
9514 1404 393
Answer:
0
Step-by-step explanation:
If a=b, you are asking for a whole number c such that ...
c = √(a² +a²) = a√2
If 'a' is a whole number, the only whole numbers that satisfy this equation are ...
c = 0 and a = 0.
0 = 0×√2
The lowest whole number c such that c = √(a²+b²) and a=b=whole number is zero.
__
√2 is irrational, so there cannot be two non-zero whole numbers such that c/a=√2.
_____
Additional comment
If you allow 'a' to be irrational, then you can choose any value of 'c' that you like. Whole numbers begin at 0, so 0 is the lowest possible value of 'c'. If you don't like that one, you can choose c=1, which makes a=(√2)/2 ≈ 0.707, an irrational number. The problem statement here puts no restrictions on the values of 'a' and 'b'.
