Answer: D. 2x4+x3–x+2 is prime
Step-by-step explanation:
Answer:
The value of x is -29 and the value of y is -26
Step-by-step explanation:
we know that
If two figures are congruent, then its corresponding angles and its corresponding sides are congruent
so
The length of the corresponding sides must be equal
----> equation A
----> equation B
Note
The length of one side of the triangle equal to -5 is not logical, however we will continue with the resolution of the problem for didactic purposes.
Solve the system by graphing
Remember that
the solution of the system of equations by graphing is the intersection point both graphs
using a graphing tool
The solution is the point (-29,-26)
see the attached figure
therefore
The value of x is -29 and the value of y is -26
it’s c
Because you do 5n+3 times 5n+3 and you get 25n^2+9
Answer:
87.92 in²
Step-by-step explanation:
pi × (R² - r²) = area
Where R is the radius of the outer circle and r of the inner circle.
Since C = 2pi×r
37.68 = 2×3.14×r
r = 6 in
R = 6 + 2 = 8 in
Therefore,
pi × (R² - r²) = area
Area = 3.14 (8² - 6²)
= 87.92 in²
