Answer: The solution to the given system is
Step-by-step explanation:
The given system of equations :
To solve this , we eliminate equation (1) from (2) , we get
Put value of in (2) , we get
[∵ (-)(-)=(+)]
Hence, the solution to the given system is
Answer:
1. 6 x^2 - 28 x + 30
2. (x-6) (x+3)
b cannot see
4a 20 x^3 - 10x^2 ft^3
b 160 ft^3
Step-by-step explanation:
1. (2x-6) * (3x-5) =
6x^2 -18x-10x+30
6 x^2 - 28 x + 30 excellent job
2. x^-3x-18
what numbers multiply together to give -18 and add together to give -3
-1* 18 = -18 -1+18 = 17
-2 * 9 = -18 - 2 + 9 = 7
-3 * 6 = 18 -3 + 6 = 3
-6 * 3 = -18 -6 + 3 = -3
(x-6) (x+3) excellent
I cannot check part b because it is cut off
4. V = l * w * h
V = (8x-4) * x * 2.5x
(8x-4) * 2.5x^2
20 x^3 - 10x^2
if x=2
V = 20 (2)^3 - 10 (2)^2
V = 20*8 - 10*4
V = 160 - 40
V = 120 ft^3
Answer:
R $ 3855
Step-by-step explanation:
João comprou uma TV por R $ 2400,00; um celular por R $ 1350,00 e um tênis por R $ 130,00 qual o valor total da compra?
O preço total de compra é calculado como:
Custo da TV + Custo do Celular + Custo do Tênis
R $ 2400,00 + R $ 1350,00 + R $ 130,00,
= R $ 3855
