Step-by-step explanation:

Given

x³ + 3x² + 3x + 9 ( factor first/second and third/fourth terms )

= x²(x + 3) + 3(x + 3) ← factor out (x + 3) from each term

= (x² + 3)(x + 3) → C

Answer:

95 degrees

Step-by-step explanation:

Measure of arc AB is 360 - (101+97+69) = 360 - 267 = 93 degrees.

Measure of arc DAB is 97+93 = 190 degrees, so measure of angle C is 190/2 = 95 degrees.

Sales increased by only 12% last month. If the sales from the previous month were $152,850, what were last months sales

Tamiku [17]

Answer:

$\$171,192$

Step-by-step explanation:

Remember that

$100\%+12\%=112\%=112/100=1.12$

we know that

The sales from the previous month were $152,850

This amount represent the 100%

Find out what were last months sales, multiply the sales from the previous month by the factor 1.12

$\$152,850(1.12)=\$171,192$

Solve simultaneous equations 3x-2y=17 +2x-2y=10

Zarrin [17]

Answer:

(7;2)

Step-by-step explanation:

$3x - 2y = 17 \\ - 2y = 17 - 3x \\ 2x + 17 - 3x = 10 \\ 2x - 3x = 10 - 17 \\ - x = - 7 \\ x = 7 \\ - 2y = 17 - 21 \\ - 2y = - 4 \\ y = 2$

Sasha is bisecting a segment. First, she places the compass on one endpoint, opens it to a width larger than half of the segment

ycow [4]

Her next step is to repeat the last process of drawing those two arcs. However, they will be mirrored since she swapped endpoints.

Check out the diagram below. Figure 1 is what she already has. Figure 2 is what happens after completing the next step. The red and blue arcs intersect to help form the endpoints of the perpendicular bisector. I used GeoGebra to make the diagrams.
