answer: x= 7
Hope this helped if it did mark me brainliest
x = 2(x+2) + 3(x-1) = 3x + 7
2x + 4 + 3x -3 = 3x + 7
2x + 3x - 3x = 7 - 4 + 3
2x = 6
x = 3
Answer:
43.0°
Step-by-step explanation:
cos∅=adj/hyp

Answer:
B) 4.5
Step-by-step explanation:
The area of the first figure is 10x
The area of the second figure is 6(x+3)=6x+18
To solve, find the x that makes 10x=6x+18
1) 10x=6x+18
2) 4x=18
3) x=4.5
To check work)
1) 10(4.5)=6(4.5)+18
2) 45=27+18
3) 45=45
