Answer:
5 x 8 = 40
Step-by-step explanation:
the formula for the area of a parallelogram is a = bh. Its the same as a square or rectangle. So you just have to multiply the lenght (5) and width (8) which equals 40.
Hope this help have a great day!
Answer:
The two angles are 69° and 21°.
Step-by-step explanation:
Write out the expression:
let x and y be two angles that are complementary and the sum of their measures is 90°
-> x° + y° = 90°
if one angle is 6º more than three times the other angle:
-> x° = 6° +3y°
Plug x = 6+3y into x° + y° = 90°
6° + 3y° + y° = 90°
Solve for y
4y° = 84°
y° = 21°
Plug y into x° + y° = 90°
x° + 21° = 90°
Solve for x°
x° = 90° - 21° = 69°
3x + 5Y > 25
**we know that the sale is MORE but not equal to 25
