Answer:
[tex]A = x^{2} + x[/tex]
Step-by-step explanation:
Area of a triangle = bh/2
Your base is 2x and the height is x + 1
So, A = (2x)(x + 1)/2
A = [tex]x^{2} + x[/tex]

A square has an area of 313.29m2.
Work out the perimeter of the square.
The perimeter of the square is 70.8 meters.
To find the perimeter of a square, we need to know either the length of one side or the area of the square. In this case, we are given the area of the square as 313.29 m².
The formula for the area of a square is:
Area = side length²
We can rearrange this formula to solve for the side length:
Side length = √Area
Substituting the given area into the formula, we have:
Side length = √313.29 m²
Calculating the square root of 313.29, we find that the side length of the square is approximately 17.7 meters (rounded to one decimal place).
Since a square has four equal sides, the perimeter is simply four times the side length:
Perimeter = 4 * 17.7 m = 70.8 meters
As a result, the square's circumference is 70.8 metres.

85
110 of the coins are 50p
110 x .5 = 55
85 + 55 = 140

Write an equation for the nth term of each arithmetic sequence: 45, 30, 15, 0, …
Answer:
[tex]a_{n}[/tex] = 60 - 15n
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 45 and d = a₂ - a₁ = 30 - 45 = - 15 , then
[tex]a_{n}[/tex] = 45 - 15(n - 1) = 45 - 15n + 15 = 60 - 15n
An equation for the nth term of the arithmetic sequence is aₙ=60-15n.
What is an arithmetic sequence?An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same. The general form an arithmetic sequence is aₙ=a+(n-1)d.
The given arithmetic sequence is 45, 30, 15, 0,.....
Here, a=45 and d=30-45 = -15
Now, aₙ=45+(n-1)(-15)
aₙ=45-15n+15
aₙ=60-15n
Therefore, an equation for the nth term of the arithmetic sequence is aₙ=60-15n.

A triangle has sides that are 3, 7, and squareroot 57. Is the triangle a right triangle?
Answer:
my answer is no because for a right angle triangle the sum of the squares of the other two sides is equal to the square of the longest side
3²+7²=9+49=58
(√57)²=57
57≠58 it's not a right angle triangle
assume the sides to be a,b and c
a=3 b=7 c=√57
by Pythagoras theorem
a²+b²=c²
3²+7²=√57²
but 58≠57

3(4x+6)=x-4
Answer:
x = −2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(4x+6)=x−4
(3)(4x)+(3)(6)=x+−4(Distribute)
12x+18=x+−4
12x+18=x−4
Step 2: Subtract x from both sides.
12x+18−x=x−4−x
11x+18=−4
Step 3: Subtract 18 from both sides.
11x+18−18=−4−18
11x=−22
Step 4: Divide both sides by 11.
[tex]\frac{11x}{11}[/tex] = [tex]\frac{-22}{11}[/tex]

Answer:
D. Neitherx- intercept: (-13/6, 0), y- intercept: (0, 13)(-1, 3)Step-by-step explanation:
#1
y = -2x - 5Substitute pairs of solutions and verify
(1, 7)
7 = -2*1 - 57 = -7Wrong(2, -7)
-7 = -2*2 - 5-7 = -11WrongCorrect choice is D. Neither
#2
y = 6x + 13x- intercept: y = 0
6x + 13 = 06x = -13x = -13/6(-13/6, 0)y- intercept: x = 0
y = 6*0 + 13y = 13(0, 13)#3
y - 3 = 2(x + 1)x = -1 ⇒ find y:

For numbers 11-16 Find x, y, and z for each. Show all work.
Answer:
x=74
y=37
z=25
Step-by-step explanation:
First, we can find y.
106 and 2y are supplementary angles. That means that when added together, they equal 180.
106+2y=180
2y=74
y=37
We can use this information to help us find x.
x and 2y are corresponding angles, which means that they are congruent.
2y=x
2(37)=x
74=x
Now, let's find z.
4z+6 is corresponding to the angle right above angle x. This means that (4z+6)+x=180.
Let's solve.
(4z+6)+74=180
4z+80=180
4z=100
z=25
Hope this helped!
