Answer:
x³ + 3x² + 3x + 2
Step-by-step explanation:
Given
(x + 2)(x² + x + 1)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x² + x + 1) + 2(x² + x + 1) ← distribute both parenthesis
= x³ + x² + x + 2x² + 2x + 2 ← collect like terms
= x³ + 3x² + 3x + 2
Answer:
120
Step-by-step explanation:
The first part of the second line, she left the -5 there. The correct work and solution should be this:
5(2x-1)-3x=5x+9
<span><span>7x</span>−5</span>=<span><span>5x</span>+<span>9
</span></span>2x-5=9
2x=14
x=7
Answer:
1 =98
2 = 49
3 = 63
Step-by-step explanation:
Assuming 1 is at the center since it has the dot
<1 = arc 98
<1 = 98
We can find angle 2
<2 = 1/2 the intercepted arc
<2 = 1/2 (98)
<2 = 49
We can find angle 3
Angle formed by 2 chords
<3 = 1/2(arc 70 + arc56)
<3 = 1/2(70+56)
<3 =1/2 (126)
<3 = 63
