Help!! Find the value of x
Romashka [77]

Answer:

x = 51

Step-by-step explanation:

The sum of internal angles for this rectangle is 360

x + 81 + 124 + 104 = 360 add like terms

x + 309 = 360 subtract 309 from both sides

x = 51

Given the function f(x) = 4(2)x, section a is from x = 1 to x = 2 and section b is from x = 3 to x = 4. part
Aliun [14]
A. Average rate of change for x=1 to 2: 4(2²)-4(2)=16-8=8; from x=3 to 4: 4(2⁴)-4(2³)=64-32=32.
b. Section b is 32/8=4 times greater. As the exponent of 2 increases, the gaps between consecutive powers of 2 gets wider and therefore the rate of change is greater.

an apple orchard contains a hundred and twelve trees the number of trees in each row is 2 less than twice the number of rows fin
san4es73 [151]
Let x be the number of rows and y be the number of trees per row.

x* y = 112
and y =  2x - 2
from first equation  y = 112/x
so  112/x = 2x - 2
112 = 2x^2 - 2x
2x^2 - 2x - 112 = 0
x^2 - x - 56 = 0
(x - 8)(x + 7) = 0
x = 8 , - 7   (ignore the negative)
so the number of rows = 8 
and number of trees per row = 112/8 = 14

Answer number of rows = 8 and number trees i each row = 14.
