Follow the definition of exponents and the rules of multiplying positive and negative numbers.

$(-2)^4 = (-2)(-2)(-2)(-2) = 4(-2)(-2) = -8(-2) = 16$

$-2^4 = -(2^4) = -[2(2)(2)(2)] = -[4(2)(2)] = -[8(2)] = -[16] = -16$

Answer: The third choice, 16 and -16

Answer: 18.7

Step-by-step explanation:

Find the lengths of AB, BC, and CA

AB = $\sqrt{(4-(-1))^{2} + (-1-4)^{2} }$ = 5 $\sqrt{2}$ ≈ 7.1

BC = $\sqrt{(0-(-1))^{2} + (-3-4)^{2} }$ = 5 $\sqrt{2}$ ≈ 7.1

CA = $\sqrt{(0-4)^{2} + (-3-(-1))^{2} }$ = 2 $\sqrt{5}$ ≈ 4.5

7.1 + 7.1 + 4.5 = 18.7

Can anybody help me???

Tasya [4]

#10

$\\ \rm\longmapsto 0$

#11

Last three i.e Option B,C,D

#13

It started from negative ends at positive hence

$\\ \rm\longmapsto y=-|x|+2$

#14

(-3,-10)

$\\ \rm\longmapsto 2(-3)-(-10)=4$

$\\ \rm\longmapsto -6+10=4$

Proved

#15

(1,1)

$\\ \rm\longmapsto 1=(1-2)^2=(-1)^2=1$

#16

(2,-4)

$\\ \rm\longmapsto -2-2(-4)>3$

$\\ \rm\longmapsto -2+8>3$

$\\ \rm\longmapsto 6>3$

A rectangular greenhouse has an area of 6480 square meters and a length of 120 meters. How many meters is it in width?

bonufazy [111]

Area is length x width. If the area is 6480, and you know the length, plug it into the formula to find the width.

120 x width = 6480

So, to solve, you would divide 6480 by 120 to find the width. 6480/120 = 54.

Therefore, the width is 54.
