Coefficient of the quadratic term clearly is -4 (ALTERNATIVE 2)
Least common multiplue is the smallest number that the 2 numbers can multiply into so exg LCM of 3 and 2 is 6,
to find, find the factors
12=2 times 2 times 3
18=2 timeds 3 times 3
so combine all of them
in 12, we have 2 2's and 1 three
in 18, we have 1 2 and 2 3's so
we must have 2 2's and 2 3's so
2 times 2 times 3 times 3=36=lcm\
so find factors and group
lcm=36
Answer:91
Step-by-step explanation:
If the best grade is 100,91 is it.
Answer:
R = 4cm
Step-by-step explanation:
V = π(R)²h = 480π
Divide by π
(R)²h = 480
Substitute h with 30
30*(R)² = 480
Divide by 30
(R)² = 16
Square root
R = 4cm
We do not accept R= -4 because it's a length, so it must be positive.
Answer:
D. none
Step-by-step explanation:
The figure shows two triangles. We see a right angle in each triangle. All right angles are congruent. One angle of one triangle is congruent to one angle of the other triangle. We are not given any other information about congruent sides or other congruent angles. Therefore, there is not enough information to prove the triangles are congruent.
Answer: none
