For prisms, use the formula: 2B + Ph

B = base of figure, here it is the trapezoid.
The area of the trapezoid is (3+6)*4/2 = 18

P = perimeter of the base, which is 3+4+5+6 = 18
h = height, here it is 5.

Thus the answer is:
2*18 + 18*5 = 36 + 90 = 126 cm^2

X - 2/5 = 1/3 <br> what is x?<br> thanks x
Bogdan [553]

Isolate x. First, add 2/5 to both sides

x - 2/5 (+2/5) = 1/3 (+2/5)

x = 1/3 + 2/5

to simplify, find common denominators (15 in this case). Multiply the same number to both the denominator and numerator

(1/3)(5/5) = 5/15

(2/5)(3/3) = 6/15

x = 5/15 + 6/15

Simplify

x = 11/15

11/15 is your answer for x

hope this helps

Find the Relative Change in the values of the function f(x) = x3 + 2 between x = 1 and x = 2.5 Enter your answer accurate to thr
ehidna [41]

Answer:

9.750

Step-by-step explanation:

formula for average rate of change is ;

f(b)- f(a)/b- a

here a = 1 and b = 2.5

f(b) = (2.5)^3 + 2 = 17.625

f(a) = 1^3+ 2 = 3

using the formula above, we have it that

(17.625-3)/2.5-1 = 9.750
