What is the area of the rhombus?
Answers
360 squared centimeter.
Answer:
Step-by-step explanation:
(-6 , 1) & (8 , 1)
d1 = 8 + I - 6I = 8 + 6 = 14
(1,6) & (1 , -4)
d2 = 6 + I -4 I = 6 + 4 = 10
Area of rhombus = [tex]\frac{d_{1}*d_{2}}{2}[/tex] where d1 & d2 are the diagonals
[tex]\frac{14*10}{2} = 7 * 10 = 70 \ square \ units[/tex]

7(3b-1)=2b-26 please help and give me step by step ☺️
Answers
Answer:
b = -1
Step-by-step explanation:
7(3b-1): 7 goes into the numbers by multiplying. This will give you 21b-7.
So now the equation should be like 21b-7=2b-26.
-7 and 2b swap places, making 21b-2b=7-26. It will give you 19b= -19.
Finally divide the two numbers (-19 / 19) and the solution will be b= -1.
If I didn't make a clear answer or a good explanation, please comment. I sometimes mess up my steps, and this is my first time using this.
Answer:
b = -1
Step-by-step explanation:
7(3b -1 ) = 2b - 26
First, distribute.
21b - 7 = 2b - 26
Then, add 7 to both sides AND subtract 2b on both sides
21b - 7 + 7 - 2b = 2b - 2b - 26 + 7
Add common terms
19b = -19
Divide by 19
b = -1

Answer:
B.The quotient is undefined because the denominator is zero.
Step-by-step explanation:
You cannot divide by zero. Take a piece of paper and divide into zero pieces. It cannot be done as we know it. That is undefined.
The quotient is undefined because the denominator is zero.

If a quadratic equation is written in intercept form, y = (x-3)(x+5), then vertex is at...
Answers
Answer:
The vertex is at (-1, -16).
Step-by-step explanation:
We are given the quadratic equation:
[tex]y = (x-3)(x+5)[/tex]
And we want to find its vertex.
Recall that the x-coordinate of the vertex is also the axis of symmetry. Since a parabola is symmetric about the axis of symmetry, the axis of symmetry is halfway between the two roots.
From the equation, we can see that our two roots are x = 3 and x = -5.
Hence, the axis of symmetry or the x-coordinate of the vertex is:
[tex]\displaystyle x = \frac{(3) + (-5)}{2} = -1[/tex]
To find the y-coordinate of the vertex, evaluate the equation at x = -1:
[tex]\displaystyle \begin{aligned} y(-1) &= ((-1)-3)((-1)+5)\\ &= (-4)(4) \\&= -16\end{aligned}[/tex]
Hence, the vertex is at (-1, -16).

Factor the polynomial completely using the
X method.
x2 + 16x + 48
An x-method chart shows the product a c at the top of x and b at the bottom of x. Above the chart is the expression x squared + 16 x + 48.
Answers
The factors of the polynomial x² + 16x + 48 are ;
-4 and -12.
Given the polynomial :
x² + 16x + 48
To factorize :
x² + 16x + 48 = 0
Two numbers whose addition gives 16 and product gives 48
The two numbers are : 12 and 4
x² + 12x + 4x + 48 = 0
x(x + 12) + 4(x + 12)
Hence,
(x + 12) = 0
(x + 4) = 0
Hence,
x = -4 or x = -12
