The 1st layer has 1 cubes, which is also 1²,
the 2nd layer has 4 cubes, which is 2²
the 3rd layer has 9, which is 3²
the nth layer has n² cubes
Answer:
h=0
Step-by-step explanation:
-4(h-2)=8
/4 /4
h-2=-2
h=0
Hey Btw I strongly reccomend you use photomath for your math classes.
The question is incomplete.
The complete question is:
Given the functions j(x) = x² − 9 and k(x) = −x + 7, which operation results in a 3rd degree polynomial?
Answer: the multiplication of j(x) and k(x)
Explanation:
<span>1) j(x) × k(x) = (</span><span>x² − 9) ( − x + 7)</span>
<span>2) Use distributive propery:
</span>
<span>(<span>x²)(- x) + (x²) (7) + (-9)(-x) + (− 9) ( 7) = - x³ + 7x² + 9x - 63
</span></span><span><span>
</span></span><span><span>
</span></span><span><span>The exponent of x is 3, hence this is a third degree polynomial.
</span></span>
Answer:
hi, first question's answer B.
because if you want to draw a triangle, there is have to be some rules. like can you draw a triangle 2,2,20? that could be impossible because all the edges have to intersect. think a triangle and it has 3 edges. they are A,B,C
if you wanna write random numbers, you have to do this.
A+B>C>|A-B|
A+C>B>|A-C|
C+B>A>|C-B|
soo, 7+11= 18 and 11-7=4
second question's answer is this:
60+x+32+90=180(if you wonder where is the 90 came from, the triangle's one side has square. that mean its 90°.
182+x=180
x=-2
if you have questions about these questions, you can ask me.
good luck(:
