Answer:
1. 2x−11
2. x²−2x−8
Step-by-step explanation:
1.
Regroup terms.
Expand by distributing terms.
Collect like terms.
Simplify.
2.
Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd(a+b)(c+d)=ac+ad+bc+bd.
Answer: The answer is D
If you read all the answers only D is true
4: 20 cm3
6 x 4 = 24
24 x 10 = 240
it is cubic since it is volume
-4x+3>-5
or, -4x>-5-3
or, -4x>-8
or, -4x/-4<-8/-4
so, x<2
That would be zero.
Obtuse means more than 90 degrees. A triangle's angles add up to 180 degrees so can't have two obtuse angles.
