Answer:
25.28
Step-by-step explanation:
this problem is an inequality stating that 6.32 is at least greater than 1/4 of some number, n
1/4n < 6.32
n < 6.32(4)
n < 25.28
Area= (a+b/2)(h) is the formula
Answer:
Part A : y²(x + 2)(x + 4)
Part B: (x + 4) (x + 4)
Part C: (x + 4) (x - 4)
Step-by-step explanation:
Part A: Factor x²y²+ 6xy²+ 8y²
x²y²+ 6xy²+ 8y²
y² is very common across the quadratic equation , hence
= y² (x² + 6x + 8)
= (y²) (x² + 6x + 8)
= (y²) (x² + 2x +4x + 8)
= (y²) (x² + 2x)+(4x + 8)
= (y²) (x(x + 2)+ 4(x + 2))
= y²(x+2)(x+4)
Part B: Factor x² + 8x + 16
x² + 8x + 16
= x² + 4x + 4x + 16
= (x² + 4x) + (4x + 16)
= x( x + 4) + 4(x + 4)
= (x + 4) (x + 4)
Part C: Factor x² − 16
= x² − 16
= x² + 0x − 16
= x² + 4x - 4x - 16
= (x² + 4x) - (4x - 16)
= x (x + 4) - 4(x + 4)
= (x + 4) (x - 4)
Answer:
Whats the question
Step-by-step explanation:
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
