Answer:
x^2 +8x
Step-by-step explanation:
2x+x(x+6)
Distribute
2x + x^2 +6x
Combine like terms
x^2 +8x
Substitute 21 for x.
y = 21 - 4 = 17
What are you trying to solve for? Area, perimeter, volume?<span />
2(4x+5)>7x+20 perform indicated multiplication on left side
8x+10>7x+20 subtract 7x from both sides
x+10>20 subtract 10 from both sides
x>10
or in interval notation, x=(10, +oo)
Answer:
C
Step-by-step explanation:
In order to prove congruency using SSS, we need to prove that all three pairs of sides are congruent.
We are already given that EF ≅ HI and that FG ≅ IJ.
Therefore, the last bit of information we need to prove congruency using SSS is that EG ≅ HJ.
Hence, our answer is C.
