Answer:
1) D.208
2) C.112
Step-by-step explanation:
so basically for 1 you solve the area for all the shapes you see in the net using the equation l*w=a and add them together
l= length
w=width
a=area
4*8=32
4*8=32
6*4=24
6*4=24
6*8=48
6*8=48
48+48+24+24+32+32=208
208
for number 2 since it's lateral surface area, you wanna find the area of all the shape in the net except for the square in the middle.
for the triangles you're gonna wanna use the equation 1/2b*h=a
b= base
h=height
a=area
7*4=28
7*4=28
7*4=28
7*4=28
28*4=112
Answer:
True: B, C and D
Step-by-step explanation:
The graph of the function is shown in the attached diagram.
The vertex of the parabola (parabola is the graph of the function f(x)) is at (-3,-16), because
So, option A is false and option B is true.
As you can see from the graph, the function is increasing for all x>-3, thus option C is true.
The graph is positive for x<-7 and x>1 and negative for -7<x<1, so option D is true and option E is false.
Answer:
x = 12
Step-by-step explanation:
Step 1: Add 9 to both sides.
Step 2: Divide both sides by 7.
Step 3: Check if solution is correct.
Therefore, x = 12.
