Answer:

x = 60

Step-by-step explanation:

The sum of exterior angles in a rectangle is equal to 360

so to find the value of x we need to use all given values and write an equation:

x + 2x + x + 2x = 360 add like terms

6x = 360 divide both sides by 6

x = 60

Find the missing side lengths. All answers should be in fully simplified form.<br> a=?<br> b?

Alekssandra [29.7K]

Answer:

a=8 b=6

Step-by-step explanation:

Using the Pythagorean theorem, a^2+b^2=c^2, and in this case, a^2+b^2=10^2 = 100

so a^2+b^2=100

8^2+6^2=100

64+36=100 ✔

and since A is longer than B, a=8, b=6

Answer:

2. $-x^{2} +3x+15$

3. $-x^{2} -x+9$

Step-by-step explanation:

We add like terms together to simplify

2. 3x²-4x²= -x² -2x+5x= 3x 6+9= 15 all equal to -x²+3x+15

3. 2x²-3x²= -x² 6x-7x= -x 8+1=9 all equal to -x²-x+9

If x = 5 and 5 = y, then x = y

garri49 [273]

You are right. Transitivity means, that:
if a = b and b = c, then a = c
(here a = x, b=5 and c = y).
