Both of them together have 690 because you subtract 152 from 421 so...
421-152=269
Then add 269 to 421
421+269=690
Answer:
do 70x70=4,900 than do 100 x100=10,000 than add them to gether and you get 10,4900
Step-by-step explanation:
theres 2 sides not just one
Here are a bunch of CORRECT answers. Your answer is in the first pic. I got number 3 wrong, but it still showed the correct answer.
The shape of the cross-section formed is a triangle, when a cone is cut in such a way that the cross-section is perpendicular to the base and it passes through the vertex.
Considering it's critical points, it is found that the least possible degree of the polynomial graphed above is of 4.
<h3>What are the critical points of a function?</h3>
The critical points of a function are the values of x for which:

In a graph, they are the turning points, and if a function has n critical points, the least possible degree is of n + 1.
In this problem, the function has 3 turning points, at x = -3, between x = -3 and x = 3, and at x = 3, hence the least possible degree of the polynomial graphed above is of 4.
