52s + 30b because 52 x s + 30 x b = 52s + 30b
Answer:
2kg
Step-by-step explanation:
Let the sum of the other 2 bricks be R. Given that the heaviest brick weighs 2/3 times as much as the other 2 bricks in total, then the weight of the heaviest brick H in terms of the weight of the other 2 will be
H = 2/3 * R
= 2R/3
Given that the 3 bricks weigh 5kg in total then,
2R/3 + R = 5
Multiply through the equation by 3
2R + 3R = 15
5R = 15
Divide both sides by 5
R = 15/5
= 3
The weight of the heaviest brick is 2R/3. Since R = 3, the heaviest block weighs
= 2 * 3/3
= 2kg
Answer:

Step-by-step explanation:
The zeros of the polynomial function are given us as -5,-1,2
If the zeros of a polynomial function are α,β,ω, the polynomial function can be obtained using the expression below:
f(x) = (x - α)(x - β)(x - ω)
where α = -5, β = -1, and ω = 2
