(5x4) + (2x-7)
20 + -14 =6
Answer:
12 BTU
Step-by-step explanation:
1 decimeter is 10 centimeter so you divide 27 by 10 and get 2.7
So she cut 2.7 decimeter off her hair
To find the area of the triangle, you need to do 9*8=72 then divide by 2 to get 36. to find the area of the square you do 5*5=25. subtract 36-25 to get 11. the area of the unshaded region is 11 centimeters squared.
3x+2y=9
3x+2(4x-1)=9
11x-2=9
+2 +2
11x=11
X=1
Y=4x-1
Y=4(1)-1
Y=3
