Answer:
(4+x)^2
Step-by-step explanation:
Rewrite 16 as 4^2
4^2+8x+x^2
Check the middle term by multiplying 2ab and compare the result with the middle term in the original expression.
2ab=(2)x(4)x(x)
Factor using the perfect square trinomial rule a^2+2ab+b^2=(a+b)^2, where a=4 and b=x
Anwser:
(4+x)^2
Hopefully that is the correct anwser you're looking for!
Answer:
B
Step-by-step explanation:
First
Get totals for food items:
Pizza $14.95 ×2=$29.90
Salad=$4.35
Drinks $2.49 ×4=$9.76
Total Bill
$29.90
$ 4.35
<u>+</u><u>$</u><u> </u><u>9.76</u>
$44.21 Food Bill
Second Step
Find Tip Amount Before Tax
Total Bill $44.21 × .15=$6.63 Tip
Third Step
Find Tax on Total Food Bill
$44.21 × .07675=$3.39
Fourth Step
Find amount left from paying bill with tax.
Total Bill including tax:
$44.21 (bill) +$3.39 tax=$47.60
Cash $ 50.00
Total Bill - $<u>47.60</u>
$ 2.40 Change left over
Fifth Step
Find amount needed to give $6.63 tip from above.
We have $2.40 we need $6.63
Subtract $6.33 -$2.40=$4.23 more money needed for tip
Answer:
is neither lost or gained
Step-by-step explanation:
The law of conversation tells us that energy can't be created or destroyed. So, the total energy of an isolated system should be constant.
This also works for momentum. When 2 objects collide, their total momentum will not change. Some of the energy can be transferred which change the momentum of individual object, but not the sum/total.
To find the height you need to take the volume, and the radius (halve the diameter to get the radius) and use the same formula that would be to find Volume and when you plug in the volume and radius you take the radius and solve it with the exponent. Then you take the solved radius and you multiply it with 3.14. After that you then divide the volume by the multiplication.
V=(3.14)(r^2)h
Example:
V=87.92m^3
pi=3.14
r=2m
h=?
87.92=(3.14(2)^2)h
87.92=(3.14(4))h
3.14*4=12.56
87.92/12.56=7
h=7m
You would need 31 Vans for everyone to be transported.
