Step-by-step explanation:
Compare the longest side to the other 2 shorter sides of the triangle:
10² : 7² + 8²
= 100 : 113
Since 7² + 8² > 10², it is an acute triangle.
To find the area its LW or Length times Width.
so you'd do 10x8
10x8=80.
The answer for that question would be 80 yards
Answer:
if x gets +2 then y gets 3 taken away
5 units over
with a scale factor of .5
What this is asking is how do you turn the one shape into the other. The first answer is how many spaces apart they are. In this case the smaller rectangle EHGF was 5 units (or squares over... Also note that the fact that the larger rectangle is higher doesn't matter because the space is reduced when it is shrunk). The second answer was talking about how much smaller it was. This is identified by counting the sides. rectangle EHGF had sides 1 unit (square) and 2.5 units (squares) long this is half or .5 of the larger ABCD's 2 units (squares) and 5 units (squares).
Answer:
y=5 or y=−5 it does not matter either one
Step-by-step explanation:
25=y2
Step 1: Subtract y^2 from both sides.
25−y2=y2−y2
−y2+25=0
Step 2: Subtract 25 from both sides.
−y2+25−25=0−25
−y2=−25
Step 3: Divide both sides by -1.
−y2
−1
=
−25
−1
y2=25
Step 4: Take square root.
y=±√25
y=5 or y=−5
