The triangles are similar so ∆JKL is just an enlargement of ∆WVU. Therefore the ratios of the side lengths are the same. 10:20 = 1:2 so the side lengths for ∆JKL must be in the ratio 1:2. 15 × 2 = 6x so 30 = 6x so x = 5

Answer:

$\frac{a^2}{b^2}$

Step-by-step explanation:

Apply the exponent rule $a^b*a^c=a^b+c$ to a

$a^4*a^-^2=a^4^-^2=a^2$

$b^3a^2b^-^5$

Apply the exponent rule to b

$b^3*b^-^5=b^3^-^5=b^-^2$

Apply the exponent rule $a^-^b=\frac{1}{a^b}$

$b^-^2=\frac{1}{b^2}=\frac{1}{b^2}a^2=\frac{a^2}{b^2}$

The sum of three numbers is 24. the largest number is three times the smallest, and the middle number is four less than the larg

tensa zangetsu [6.8K]

Small number =X
mid number = 3X-4
large number = 3x

X+3X-4+3X=24
7X-4=24
7X-4+4=24+4
7X=28
X=28/7
X=4

S=4
M=3(4) -4=12-4=8
L=3(4)=12

The numbers are 4,8 and 12

As – 16a,<br> as – 4a3,<br> 2a3 + 8a - 4a2 - 16

vfiekz [6]

Answer:

1) as-16a

taknig a as common

=a(s-16)

2)as-4a³

taking a as common

=a(s-4a²)

3)2a³+8a-4a²-16

taking common terms

=2a(a²+4)-4(a²+4)

=(2a-4)(a²+4)

again taking common

=2(a-2)(a²+4)

i hope this will help you :)

Place these numbers in greatest to least, 15%, 1/8, 0.2, and 0.09 QQQQQUICKLY PLEAS!

snow_lady [41]

Hey there.

15% is equivalent to 0.15 and 1/8 is equivalent to 0.125. Let's set these from greatest to least:

0.2, 0.15 (15%), 0.125 (1/8), 0.09.

I hope this helps!
