Answer: C 20
Explanation: Plug in 2 for k.
2^2 - (2-10) + 4(2) = 20
Answer:
100°
Step-by-step explanation:
we know that a 90 degree angle looks like a capital L and this like a tab bit larger,so 100 degress
Assuming that means the diameter is 6in
so then
vsphere=(4/3)pir^3
r=d/2
d=6
6/2=3=r
vcube-vsphere=space
vcube=side^3=6^3=216
vsphere=(4/3)pi3^3=36pi=113.093755
space=216-113.083755=102.9026644707 cubic inches of empty space
Answer:
D. Step 1 only.
Step-by-step explanation:
Here, Josie didn't use the distributive property correctly. The other two steps are still right, so D is correct.
How it should have been done:
x + 3 + 7x(x - 5)
<em>Use the distributive property to multiply 7x by x - 5.</em>
x + 3 + 7x² - 35x (The boldened part is what should have happened for Step 1)
<em>Combine x and -35x to get -34x.</em>
7x² - 34x - 3 is what the earlier equation should be simplified to.
