Answer:
x = ±2.24
Step-by-step explanation:
16x² - 80 = 0
16x² = 80 (Add 80)
x² = 5 (Divide by 16)
x = ±√5 (Square root both sides)
≈ 2.24, -2.24
180 -134 = 46 is PRQ
46 x 2 = 92 is POQ acute angle
360 - 92 = 268 is POQ reflex angle
Answer:
The answer is Area=24
Step-by-step explanation:
You use the formula B*H/2=A
So 12*4=48/2=24
Hope this helps!
Answer:
The number of wrapping paper sold was 32 and the number of magazines sold was 40
Step-by-step explanation:
Let
x ----> the number of wrapping paper sold
y ----> the number of magazines sold
we know that
The classes sold 72 items
so
----> equation A
The classes earned $222 for their school
so
----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
using a graphing tool
The solution is (32,40)
see the attached figure
therefore
The number of wrapping paper sold was 32 and the number of magazines sold was 40
