First you simply have to substitute 2 in replace of all the a's, and -2 in replace of all of the b's
4((2)2+2(-2))
Then you want to follow the order of operations, PEMDAS (Parantheses-Exponent-Multiplication-Division-Addition-Subtraction), and multiply within the parantheses.
4(4+(-4))
Next you will add within the parantheses (So add the 4 and -4 together)
4(0)
Lastly multiply
0
Your answer is 0
Hope this helps!
Answer:
They are both right triangles
Step-by-step explanation:
The triangles are both the same shape but one is bigger than the other.
Answer:
x > 6
Step-by-step explanation:
Given
3x + 10 > 28 ( subtract 10 from both sides )
3x > 18 ( divide both sides by 3 )
x > 6
Answer:
It is right
Step-by-step explanation:
Because the hypotenuse must be greater than all the legs, we have that 
is the hypotenuse. So, we want to determine if 
.
This means the triangle is indeed right!
