How I Was Taught You Do Foil F-First O-Outer I-Inner L-Last So You Would Multiply First Number With The Other First Number Which Is The 4b×4b=16b² Then You Solve The Outer 4b+1 Then The Inner -1+4b & The Last -1+1

Answer:
1) True 2) True 3) False 4) True
Step-by-step explanation:
In this question let's verify those options
1.Triangle A B C is inside triangle D E F. (true)
If A, B and C are midpoints of DEF then connecting those midpoints we have an interior triangle.
2. Point A is the midpoint of side F D, point B is the midpoint of side D E, point C is the midpoint of side F E. (true)
3. Angles D F E and A B C are right angles. (false)
These triangles are similar. And In this case, the right angles are:

D and C are opposed to the larger side, and not F, and B
Because:
4. The length of D E is 10 centimeters, the length of F D is 6 centimeters, and the length of F E is 8 centimeters. (true)
Let's test this by the Pythagorean Theorem. For DE is the hypotenuse and FD and FE is their legs.

Answer:
8
Step-by-step explanation:
if f(x)=-2 then what would you have to add to it to get 6
-2+?=6 ?=8
k=8
Answer:
45
Step-by-step explanation:
because the mass
4x-4<8
Add 4 on both sides
4x<12
Divide 4 on both sides
x<3
9x+5>23
Subtract 5 on both sides
9x>18
Divide 9 on both sides
x>2
*for reference, I will go ahead and add in that x will be greater than 2 and less than 3
2<x<3
