Answer:
x = -1 and y = 6
Step-by-step explanation:
using x = -b/2a
x = -4 / 2(2)
x = -1
y = 2(-1)² + 4(-1) + 8
y = 2 - 4 + 8
y = 10 - 4
y = 6
Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
The picture of the question in the attached figure
Part 1
Find the length side AB
we know that
----> by SOH (opposite side divided by the hypotenuse)
substitute the given values
solve for AB
Part 2
Find the length side AC
we know that
----> by TOA (opposite side divided by the adjacent side)
substitute the given values
solve for AC
First, add 1.4 to the number given.
-3.2 + 1.4 = 1.4 - 3.2 = -2.2
a.-2.2 is one of your answer
Next, subtract 1.4 to the number given
-3.2 - 1.4 = -4.6
a.-4.6 is your next answer
a. -2.2, a. -4.6 are your two answers
hope this helps
Answer: 1.9
Step-by-step explanation:
3.5 - 1.6 = 1.9
To make sure it’s the right answer;
1.9 + 1.6 = 3.5
Answer:
8
Step-by-step explanation:
First your rectangle
A = wl
A = 2 * 2
A = 4
Then one of your triangles
A = h b/2
A = 2 * 2/2
A = 2
you have 2 triangles, so the area is 4 + 4 from the rectangle
