Step-by-step explanation:
p^2-3p(3/2)^2=8+(3/2)^2
p^2-(3/2)^2=8+9/4
√(p-3÷2)^2=√(8+9÷4) take LCM and cancel out the square and square root
p-3÷2=√(32+9÷4)
p=(3+_√41÷2)
The answer is 16 because 5(2) is 10 plus 3(2) which is 6 so 10+6 is 16
Sabemos que cada niño recibe tres bolsas, por lo que dividimos 95 entre 3 y obtenemos 31 restantes 2. Debido a esto, sabemos que hay 31 niños y nos sobran 2 bolsas.
Answer:
1
Step-by-step explanation:
If you put in 12 for t, you might see what to do.
5 - 12 / 3
12 divided by 3 = 4
/ means divide
5 - 4 = 1
-x^2+105x-1050=1550
We move all terms to the left:
-x^2+105x-1050-(1550)=0
We add all the numbers together, and all the variables
-1x^2+105x-2600=0
a = -1; b = 105; c = -2600;
Δ = b2-4ac
Δ = 1052-4·(-1)·(-2600)
Δ = 625
The delta value is higher than zero, so the equation has two solutions
