I honestly believe its D but I'm not for sure. Sorry if i didn't help much
the answer is 10.6875 you divide 4. 75 and the number 100 them multiply your answer by 225
glad to help any time
Answer:
x=-4, y=2. (-4, 2).
Step-by-step explanation:
5x+6y=-8
-2x+8y=24
-----------------
2(5x+6y)=2(-8)
5(-2x+8y)=5(24)
-----------------------
10x+12y=-16
-10x+40y=120
---------------------
52y=104
y=104/52
y=2
5x+6(2)=-8
5x+12=-8
5x=-8-12
5x=-20
x=-20/5
x=-4
Answer:
22/5
Step-by-step explanation:
The sides increase but in the same ratio,
Hence opposite/adjacent for image and pre image is the same ratio.
Therefore, tanX is 22/5
Answer:
56
Step-by-step explanation:
Let's say that D is the point where AB is split, so AD = x-6 and DB = x.
And let's say that E is the point where AC is split, so AE = x+6 and EC = x+20.
Triangle ADE is similar to triangle ABC. Therefore:
(x-6) / (x-6 + x) = (x+6) / (x+6 + x+20)
Solving:
(x-6) / (2x-6) = (x+6) / (2x+26)
(x-6) (2x+26) = (x+6) (2x-6)
2x² + 26x - 12x - 156 = 2x² - 6x + 12x - 36
2x² + 14x - 156 = 2x² + 6x - 36
14x - 156 = 6x - 36
8x = 120
x = 15
So the length of AC is:
AC = x+6 + x+20
AC = 2x + 26
AC = 2(15) + 26
AC = 56
