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
Answer:
-2+5*2= -2+10/4
You get 8/4 which is 2
Step-by-step explanation:
We know that
surface area=area of the base+4*[area of one lateral triangle side]
area of the base=b²
b is the side length of the square
b=14 cm
area of the base=14²-----> 196 cm²
area of one lateral triangle side=b*h/2
b is the side length of the square
b=14 cm
h is the height of the lateral triangle side
h is equal to the slant height
h=15 cm
area of one lateral triangle side=14*15/2----> 105 cm²
surface area=196+4*[105]------> 616 cm²
the answer is
the surface area is 616 cm²
Answer:
0.3
Step-by-step explanation:
By definition: 30% = 30/100 = 0.3
