First, plug in 7 for m
|6 - 2(7)|
|6 - 14|
|-8|
since it's an absolute value, the answer will be positive
answer: 8
Answer:
Step-by-step explanation:
ΔABC & ΔADE are similar triangles
Cross multiply,
12*x = 12*4
x = 1 * 4
x = 4
Answer:63.75 ez
Step-by-step explanation:
first you multiply 10 x 8.5 and then divide by 2=85, after that you you divide by 2 =42.5 and you see the little triangle thats 42.5/2 wich is equal to 21.25 so after all of that you add 42.5+21.25 and you get the answer
Answer: 7x-y=10
Step-by-step explanation:
Given that the sides of the acute triangle are as follows:
21 cm
x cm
2x cm
Stated that 21 cm is one of the shorter sides of the triangle2x is greater than x, so it follows that 2x MUST be the longest side
For acute triangles, the longest side must be less than the sum of the 2 shorter sides
Therefore, 2x < x + 21cm
2x – x < 21cm
x < 21cm
If x < 21cm, then 2x < 42cm
Therefore, the longest possible length for the longest side is 42cm
