Answer:
-9
Step-by-step explanation:
-7x+12=75
-12 -12
-7x= 63
divide by -7 on both sides
x = -9
Answer:
20 feet
Step-by-step explanation:
Remember the Pythagorean theorem,
x^2 + y^2 = n^2
in this case
x= 16
y = 12
so substitute back into the equation
16^2 + 12^2 = n^2
256 + 144 = n^2
400 = n^2
sqrt ( 400) = n
20 = n
Answer: GEF = 30 DEF = 40
Step-by-step explanation: By angle summation we know the entire angle
GED = 70, so the smaller angles that make up GED (GEF and DEF) will have to sum up to equal GED. Using this we get:
2x + 10 + 5x - 10 = 70
From here we can combine like terms:
7x = 70
and solve for x
x = 10
Then we can plug the value of x back into the equations given to solve for GEF and DEF
GEF:
2x+10 == 2(10)+10 = 30
DEF:
5x-10 == 5(10)-10 = 40
No because 6 out of 6 is one hole in one 6 is only 1/6 of one hole
Answer: 288
Explanation:
Split the shape up into a rectangle and triangle (shown in picture).
Find the lengths of the triangle:
Height:
28 - 12 = 16
Base:
16 - 4 = 12
Find the area of the rectangle:
12 x 16 = 192
Find are of the triangle:
(12 x 16) ÷ 2 = 96
Add them together:
96 + 192 = 288
