can i have brainliest pls tyyy :)))
Answer:
-9(2p+1)
Step-by-step explanation:
-18p - 9
find the GCF (greatest common factor) for the expression.
-9
then, divide each term by the GCF
-18p / -9 -9 / -9
= 2p = 1
next, put the two terms you get when dividing into the final form of the answer:
GCF on the outside and quotients on the inside
-9(2p+1)
hope this helped! ;)
Answer: Choice C) 124 square cm
------------------------------------------------------------------
Explanation:
Let's calculate the area of the trapezoid shown
b1 and b2 are the parallel bases; h is the height of the 2D trapezoid
b1 = 2
b2 = 5
h = 1.5
A = h*(b1+b2)/2
A = 1.5*(2+5)/2
A = 1.5*7/2
A = 10.5/2
A = 5.25
The area of one 2D trapezoid is 5.25 sq cm
There are two of these trapezoids that form the base faces of the trapezoidal prism. So the total base area is 2*5.25 = 10.5 sq cm
Keep this value (10.5) in mind. We'll use it later.
------------
Now onto the lateral surface area (LSA)
It turns out that the formula for the LSA is
LSA = p*d
where
p = perimeter of the trapezoid shown
d = depth or height of the 3D trapezoid (I'm not using h as it was used earlier)
This formula works for any polygonal base. It doesn't have to be a trapezoid.
In this case the perimeter is,
p = 1.7+2+2.65+5
p = 11.35
So
LSA = p*d
LSA = 11.35*10
LSA = 113.5
Add this LSA to the base area found earlier
10.5+113.5 = 124
The total surface area is 124 square cm
Answer:
B. The distance from the retailer decreases with time, D. The distributor is 73.6 miles away from the retailer, E. The truck is traveling at a rate of 67.8 miles per hour.
Answers: B, D, E.
Step-by-step explanation:
Answer:
$776.59
Step-by-step explanation:
For this question, you must use the formula for being compounded continuously. A=Pe^r*t. A stands for your total balance, the part you are trying to find. P stands for the initial amount. E is a constant. R is the rate of interest. And t is the number of years taken. So, to fill in the formula: P is 550, t is 15, and R would be 0.023. For R, remember not to just take the percentage, you must divide the percent of interest by 100, so 2.3 by 100 to get to 0.023. The formula should know be A= (550) e^ (0.023)(15). plug that into your calculator, and you should get $776.59.
hope this helps!
