60x + 20y is the correct answer
Answer: 637 m²
Step-by-step explanation:
We need to find the area of four triangles and one square.
The square: 169 m²
A = L²
A = (13 m)²
A = 169 m²
The triangles: 468 m²
-> We have four congruent triangles. I will find the area of two (skipping the "divide by two" part of the formula) and multiply by two to find all four at once.
A = B * H
A = (13 m) * (18 m)
A = 234 m²
-
234 m² * 2 = 468 m²
Total surface area:
169 m² + 468 m² = 637 m²
Step-by-step explanation:
1.
The given equation is :
6x+2y=14
We need to write it in the function form.
Taking 2 common from both sides,
2(3x+y)=2(7)
So,
(3x+y)=7
Subtract 3x from both sides,
y+3x-3x=7-3x
y = 7-3x
So, the correct option is (c).
2. f(x) = 3x-4
We need to find f(2). Put x = 2 in the above function.
f(2) = 3(2)-4
= 6-4
= 2
The correct option is (D).
