Answer:
210 cm^2
Step-by-step explanation:
3x-1 + 4x+1 + 3x = 70
10x = 70
x = 7
Now, Area of the triangle is 1/2 * b * h
therefore,
1/2 * 3x * 3x-1
1/2 * (3*7) * (3*7 -1)
1/2 * 21 * 20
21 * 10
210
210 is the area!
Hope this helps! mark as brainliest if helped! thanks!
Substitute the y=1:
2x + 5(1) = 9
2x + 5 = 5
subtract the 5:
2x = 4
Divide by 2:
x = 2
Step-by-step explanation:
3x - x = 2x
2(x + 2) = 2x + 2
for every number of x, 2x + 2 would always be larger than 2x.
so there is no solution, since the given equation is 2x is greater than 2x + 2.
Answer:
That's easily true
Step-by-step explanation:
20x10= 200
1100-200=900
900/25=36
