Answer:
A = 42 cm²
Step-by-step explanation:
the area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
here b = 6 and h = 7 , then
A = 6 × 7 = 42 cm²
Answer:
Option D
and 
Step-by-step explanation:
step 1
<u>Find the equation of the inequality A</u>
we know that
The solution of the inequality A (dashed line) is the shaded area below the dashed line
The equation of the dashed line is 
therefore
The equation of the inequality A is 
step 2
<u>Find the equation of the inequality B</u>
we know that
The solution of the inequality B (solid line) is the shaded area below the solid line
The equation of the solid line is 
therefore
The equation of the inequality B is 
The system of linear inequalities is

Answer:
145
Step-by-step explanation:
In this geometry, the central angle (x°) and the external angle (35°) are supplementary.
x° = 180° -35°
x = 145
The equivalent is 60 over a hundred
Answer:
x = -1
Step-by-step explanation:
x = x2 -5x = 3
-5x + 2x = -3x
x = 1
(-1)2 - 5(-1) = 3
-2 + 5 = 3
