it's 400
Step-by-step explanation:
just do it like this I guess 5 × 8 × 10
Answer:
3
y=3x
Step-by-step explanation:
y=mx+b
y=3x+0
y=3x
Csc^2x-cot^2x=1
Here is why
csc^2x=1+cot^2x
so:
1+cot^2x-cot^2x=1
1=1
Answer:
Step-by-step explanation:
Area A = 15square cm
Length L = x
Width w = x - 2
Area = L × w
15 = x(x - 2)
15 = x^2 -2x
x^2 -2x - 15 = 0
Solving by factorization
x^2 - 5x + 3x - 15 = 0
(x^2 -5x) + (3x -15) = 0
x(x - 5) + 3(x - 5) = 0
(x + 3)(x - 5) = 0
(x + 3) = 0 or (x - 5) = 0
x = -3 or 5
Since x can't be negative therefore x is 5cm
Length = 5cm
Width = 5-2 = 3cm
What do you need help on, I don’t see the picture ?????
