Answer:
36 is the answer for this problem
A, A and B. Because the first one says that ''t is less than or equal to 50 '' so it can not be at least 50 ( B ).
The second one says ''x is greater than 4'' so x can not be at most 4 because the inequality is strict, there is no ''or equal to'' .
Hope this helped
Answer:
zero
Step-by-step explanation:
The answer to that question is best found by looking at the value of the <em>discriminant</em>.
For quadratic ax^2 +bx +c = 0, the value of the discriminant is ...
d = b^2 -4ac
Here, you have a=3, b=8, c=7, so the discriminant is ...
d = 8^2 -4(3)(7) = 64 -84 = -20
When the discriminant is negative, both solutions are complex (not real).
There are zero real solutions to this equation.
Answer:
a) 5
b) 18 cm²
Step-by-step explanation:
a) Fie cel mai mic număr x, de aceea următorul număr consecutiv este x + 1.
Dacă suma a două numere naturale consecutive este egală cu 11:
x + (x + 1) = 11
x + x + 1 = 11
2x + 1 = 11
2x = 11 - 1
2x = 10
x = 10/2 = 5
Cel mai mic număr consecutiv este 5, Următorul număr consecutiv este 6 (5+1)
b) Un triunghi dreptunghic isoscel are o catetă egală cu 6cm,
de aceea baza este de 6 cm și înălțimea de 6 cm
aria triunghiului = 1/2 × baza ×înălţime = 0.5 × 6 × 6 = 18 cm²
