Answer:
the area is 17 square units
Step-by-step explanation:
separate the figure into three shapes, as shown in the picture attached.
now you have a figure with the side lengths 2 by 3, and an area of 6
a figure with the side lengths 5 by 2, and an area of 10
and a figure with the side lengths 1 by 1, and an area of 1
add the three areas (6 + 10 + 1) and you'll get your total area, 17
For this case we have the following expression:
Rewriting the expression we have:
Where,
x: exponent to which we must raise the expression to obtain 7 as a result.
We have then:
The exponent must be equal to 1:
Clearing x we have:
Substituting valres:
Answer:
you must raise the expression to 2
