Answer:24cm

Step-by-step explanation:

if there is 2 sides with the same like the length is 8 and 2 sides(8*2)=16

and the width is half (8/2) =4 double for 2 sides (4*2) = 8

8+16

Answer:

$\large\boxed{x=-\dfrac{69}{2}\to x=-34\dfrac{1}{2}\to x=-34.5}$

Step-by-step explanation:

$\dfrac{2}{3}x-\dfrac{3}{4}=5+\dfrac{5}{6}x\qquad\text{multiply both sides by LCD = 12}\\\\12\!\!\!\!\!\diagup^4\cdot\dfrac{2}{3\!\!\!\!\diagup_1}x-12\!\!\!\!\!\diagup^3\cdot\dfrac{3}{4\!\!\!\diagup_1}=(12)(5)+12\!\!\!\!\!\diagup^2\cdot\dfrac{5}{6\!\!\!\diagup_1}x\\\\(4)(2x)-(3)(3)=60+(2)(5x)\\\\8x-9=60+10x\qquad\text{add 9 to both sides}\\\\8x-9+9=60+9+10x\\\\8x=69+10x\qquad\text{subtract}\ 10x\ \text{from both sides}\\\\8x-10x=69+10x-10x\\\\-2x=69\qquad\text{divide both sides by (-2)}\\\\x=-\dfrac{69}{2}$

Someone help me asap math 10

Ghella [55]

Answer:

x ≈ 25.4 Km

Step-by-step explanation:

Using the tangent ratio in the right triangle on the right

tan54° = $\frac{opposite}{adjacent}$ = $\frac{opp}{17}$ ( multiply both sides by 17 )

17 × tan54° = opp , thus

opp ≈ 23.4

-------------------------------------------

Using the cosine ratio in the right triangle on the left

cos23° = $\frac{adjacent}{hypotenuse}$ = $\frac{23.4}{x}$ ( multiply both sides by x )

x × cos23° = 23.4 ( divide both sides by cos23° )

x = $\frac{23.4}{cos23}$ ≈ 25. 4 Km ( to the nearest tenth )

Answer: 4th graph

Explanation:

3x _> 3
x _> 3/3

9x > 54
x > 6

We can write x like this:

1 <_ x < 6

Meaning that x is bigger or equal to 1 but less than 6
