Answer:
Step-by-step explanation:
- Option A
![[x+5=20]](https://tex.z-dn.net/?f=%5Bx%2B5%3D20%5D)
tells us that: When we add 5 to a variable x, we get 20. As it has a unique value for x and is completely equal to it(i.e. 15), It is an equality.
- Option B
![[x=5]](https://tex.z-dn.net/?f=%5Bx%3D5%5D)
tells us that: A variable x equals to 5. Hence, as x is unique for 5 and is wholly equal to it, it's an equality too. - Option C
tells us that: A variable x isn't 5 but lesser than it. As we cannot equate it to 5, nor we are given the nature of the variable x, it is an Inequality. - Option D
![[x+5]](https://tex.z-dn.net/?f=%5Bx%2B5%5D)
is an expression; It can't be called an equation or an inequality unless we relate it with another expression.
Answer:
The answer is the second one
im sorry if this is wrong
Step-by-step explanation:
L = 14 - 6 = 8
w = 15 - 4 = 11
P of shaded = 2(8+9) = 2 (19) = 38
answer
last one 38ft
Answer:42.98
Step-by-step explanation:
Hf=√(11^2-8^2)
Hf=√(121-64)
Hf=√(57)
Hf=7.5
11/sin90 =7.5/sinG
Sin90=1
11/1=7.5/sinG
Cross multiply
11 x sinG=7.5 x 1
11sinG=7.5
Divide both sides by 11
11sinG/11=7.5/11
sinG=0.6818
G=sin(inverse)(0.6818)
G=42.98
