The oak tree at the school was 34 feet tall. then it grew 18 feet taller. how tall is the oak tree now? explain why you would make one of the addends a tens number when solving an addition problem

For this case we have to:

Let the variable representing the initial height of the oak

Let the variable representing the final height of the oak

According to the data we have to:

If the oak tree grew 18 feet to reach the final height we have to:

Thus, the final height of the oak tree is 52 feet.

We can add the second amount to the initial one because we talk about the growth of the oak tree itself.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

is there a picture
