Answer:
D: 
= 576 + 
Step-by-step explanation:
Well you want to find what x is so you need the square root
We already have the area for one of the squares (576) which can help us find what x is.
And the bottom small square is 7 and since it's a sqaure all the sides are congruent/ same. Which means u get .
And you need to add them all up to get what x is
and is since both sides of that triangle will have the same lengths, and when u have both of those lengths its easier to find the area
Hope this helped!
Answer:
e - 5 = 18
Hope this answered your question.
Answer:
See below
Step-by-step explanation:
The three angles inside of the triangle sum to 180
11x + 4 + 3x + 78 = 180
14x +82 =180
x = 7
then B = 11x + 4 = 11(7) + 4 = 81 degrees
C = 3x = 21 degrees
Answer:
the oldest sibling is 12 years old.
The middle child is 9 years old.
The youngest child is 6 years old.
Step-by-step explanation:
Let the age of the youngest child be x
Then the oldest child will be 2x.
The middle child will be x + 3.
Since the combined age is 27;
x + 2x + x + 3 = 27
4x = 27 - 3
x = 24 / 4
x = 6
now 2x = 12 and x + 3 = 9
Answer:
We need to turn the equation into y=mx+b form.
So the equation would be:
