15 + 8 = 7, X = 8. X equals 8.
Answer:
14 m²
Step-by-step explanation:
the height of the triangle is 3 m and the base is 4 m. 3 times 4 is 12 but then you have to half that so the area of the triangle is 6 m. The area of the rectangle is 2 times 4 which is 8. 8 plus 6 is 14. So 14 is your answer.
Answer:
-5, multiplicity 3; +9, multiplicity 2; -1
Step-by-step explanation:
The roots of f(x) are those values of x that make the factors be zero. For a factor of x-a, the root is x=a, because a-a=0. If the factor appears n times, then the root has multiplicity n.
f(x) = (x+5)^3(x-9)^2(x+1) has roots ...
- -5 with multiplicity 3
- +9 with multiplicity 2
- -1
so first day and so on
7, 10, 13,....
as you can see it's an arithmetic progression
so sum for nth term= n/2 { 2a + (n-1) d}
it's the sum of the 7th term
so
7/2 { 7 ×2 + ( 7-1) 3}
7/2 × 32
7× 16
