Answer:
7x + 4y
Step-by-step explanation:
We have to write an equivalent expression of the given expression in standard form.
The expression is - 5(x - 4y) + 2(6x - 8y)
= -5(x) - 5(- 4y) + 2(6x) + 2(- 8y)
{Applying the distributive property of multiplication}
= - 5x + 20y + 12x - 16y
= (-5x + 12x) + (20y - 16y)
{Separating the x and y terms}
= 7x + 4y (Answer)
Answer:
A = 21 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = h (b₁ + b₂ )
where h is the height between bases and b₁, b₂ are the parallel bases
Here h = 3, b₁ = 9, b₂ = 5 , then
A = × 3 × (9 + 5) = 1.5 × 14 = 21 cm²
I think it would contain 0.2915 ounces of pure gold in it. sorry if my answer isnt correct
