Answer:
The scale factor is 2.
Step-by-step explanation:
Take the vertical sides of the 2 triangles.
Their length is 3 and 6 so the scale factor is 6/3 = 2.
Also we see than the horizontal lines are in the same ratio 4 : 2 = 2:1.
Answer:
71th term is 141
Step-by-step explanation:
1 + (n - 1)*2 = 141 {Use distributive property}
1 + 2n - 2 = 141
2n - 1 = 141
2n = 141 + 1
2n = 142
n = 142/2
n = 71
Answer:
6! = 720
3! - 2! = 4
6! ÷ 3! = 120
Step-by-step explanation:
I used a calculator. ^v^
F(1) = 4 is given
f(2) = 2*f(2-1)+3
= 2*f(1)+3
= 2*4+3
= 8+3
= 11
f(3) = 2*f(3-1)+3
= 2*f(2)+3
= 2*11+3
= 22+3
= 25
f(4) = 2*f(4-1)+3
= 2*f(3)+3
= 2*25+3
= 50+3
= 53
f(5) = 2*f(5-1)+3
= 2*f(4)+3
= 2*53+3
= 106+3
= 109
f(1) = 4
f(2) = 11
f(3) = 25
f(4) = 53
f(5) = 109
Answer:
<h2><u><em>
x = -6</em></u></h2>
Step-by-step explanation:
<u><em>x + 3 - 3 = -6</em></u> (3 - 3 = 0)
<u><em>x = -6</em></u>
-------------
check
-6 + 3 - 3 = -6
- 6 = - 6
the answer is good
