Answer: Fran's number is 70
Step-by-step explanation:
Let x represent Jen's number.
Let y represent Carrie's number.
Let z represent Fran's number.
When you add their numbers together you get 207. This means that
x + y + z = 207 - - - - - - - - - -1
Jen's number is 9 more than Carrie's number. It means that
y = x - 9
Fran's number is 3 less than Jen's number. It means that
z = x - 3
Substituting y = x - 9 and z = x - 3 into equation 1, it becomes.
x + x - 9 + x - 3 = 207
3x - 12 = 207
3x = 207 + 12 = 219
x = 219/3 = 73
y = x - 9 = 73 - 9
y = 64
z = x - 3 = 73 - 3
z = 70
Answer:
The multiplicity of a root affects the shape of graph of a polynomial. If a root of a polynomial has odd multiplicity, the graph will cross the x-axis at the root. If a root of a polynomial has even multiplicity, the graph will touch the x-axis at the root but will not cross the x-axis

Tbh I don't know the answer I just hope this helps
7 x 4 = 28
Santiago has a total of $28.
Answer:
x = 20
Step-by-step explanation:
3x + 6x = 180, if you make them supplementary then they will be parallel
9x = 180
x = 20
2(6*8)=96
2(6*3)=36
2(8*3)=48
96+36+48= 180 sq. in.
(The above is the answer to #2).I shouldn't give the answer to all of them, but I can explain how to do it. In order to calculate surface area, you need to find the area for all sides of the shape. For example, #2 has six sides, so you need to find the area for all six of those sides. There are two sides that are 8 x 3, two sides that are 6 x 8, and two sides that are 6 x 3. Therefore, your equation would be 2(8x3) + 2(6x3) + 2(6x8). From that you get 48+36+96 = 180 square inches (sq. in.)
