Answer:
18
Step-by-step explanation:
Substitute x = - 3 into the expression
2x²
= 2(- 3)²
= 2 × 9
= 18
<span>x2 + 9x + 20
Factor the equation
(x+5) * (x+4)
x = -5
x = -4

Answer:
∠XMZ = 74°
Step-by-step explanation:
Since the arcs XZ and BC are congruent, then
∠BNC = ∠XMZ ← substitute values
6x - 88 = 3x - 7 ( subtract 3x from both sides )
3x - 88 = - 7 ( add 88 to both sides )
3x = 81 ( divide both sides by 3 )
x = 27
Hence
∠XMZ = 3x - 7 = (3 × 27) - 7 = 81 - 7 = 74°
Answer:
5+6+7=18, so the greatest of these integers is 7.
Step-by-step explanation:
Consecutive integers are numbers that come one right after the other, in chronological order, so by figuring out which numbers add up to 18 that go in chronological order, you will be able to find your greatest integer.
