The parallelogram shown below has an area of 21 units 2. Find the missing base B=what units

Jobisdone [24]

Answer:

b = 3 units

Step-by-step explanation:

Area of a parallelogram = base × height

Thus,

Area = 21 units²

base = b

height = 7

Plug in the value into the formula

Thus:

21 = b × 7

Divide both sides by 7

21/7 = b

3 = b

b = 3 units

Answer:

Step-by-step explanation:

$\left\{\begin{array}{ccc}4x-y=-15&\text{multiply both sides by (-2)}\\3x-2y=-10\end{array}\right\\\underline{+\left\{\begin{array}{ccc}-8x+2y=30\\3x-2y=-10\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad\qquad-5x=20\qquad\text{divide both sides by (-5)}\\.\qquad\qquad\boxed{x=-4}\\\\\\\text{Put the value of x to the first equation.}\\\\4(-4)-y=-15\\-16-y=-15\qquad\text{add 16 to both sides}\\-y=1\qquad\text{change the signs}\\\boxed{y=-1}$
