Answer:
-1.5
Step-by-step explanation:
8÷12 is 1.5 and 4÷12 is 3 so 1.5-3 is -1.5
After reading the problem, you are often asked to solve it.
Answer:
The numerical value of the circumference is greater than the numerical value of the area.
Answer:
B.
Step-by-step explanation:
y = x^2 - x - 12
y = (x-4)×(x+3) that means x it either 4 or -3
y = x + 3
for x = 4 ➡ y = 3+4 ➡7
for x = -3 ➡ y = -3 + 3➡0
(the answer key is most probably faulty there's no way for y to be 0 in both scenarios)
Answer:
48 cm²
Step-by-step explanation:
Let's call the width and height of the rectangle w and h.
w / h = 3 / 4
2w + 2h = 28
Solve the system of equations with substitution.
w = 3/4 h
2 (3/4 h) + 2h = 28
3/2 h + 2h = 28
7/2 h = 28
h = 8 cm
So the width is:
w = 3/4 (8)
w = 6 cm
So the area is:
A = wh
A = 48 cm²
