Hello from MrBillDoesMath!
Answer:
x = 12
Discussion:
From the diagram, the two triangles appear to be similiar. Then
28/7 = (6x + 28) /25
as the ratio of corresponding parts of similar triangle are the same.
28/7 = (6x +28)/25 => simplify. 28/7 = 4
4 = (6x + 28)/25 => multiply both sides by 25
4*25 = 6x + 28 => simplify, 4 * 25 = 100
100 = 6x + 28 => subtract 28 from both sides
100 -28 = 6x => simplify. 100 - 28 - 72
72 = 6x => divide both sides by 6
72/6 = 12 = x
Thank you,
MrB
Answer:
See below
Step-by-step explanation:
Vertices are the black dots of the figure:
Point Q is at (1,4)
Point R is at (3,-2)
Point S is at (0,-1)
Point T is at (-2,2)
I'm guessing it's like this
example
18=2*3*3=(2¹)(3²)
315/5=63
63/3=21
21/3=7
factored form is 3*3*5*7=(3²)(5¹)(7¹)
Answer:
a₁ = 6
Step-by-step explanation:
The sum to n terms of a geometric sequence is
=
where a₁ is the first term and r the common ratio
Here = 1530 and r = 2, thus
= 1530 , that is
a₁ (256 - 1) = 1530
255a₁ = 1530 ( divide both sides by 255 )
a₁ = 6
