Answer:</h2><h2>
The height of the triangle = 4cm</h2>
Step-by-step explanation:
Given, area of the triangle = 10 
Let the height of the triangle be h cm
Given, the base b is 3 cm less than twice its height.
b = 2h - 3 ... (1)
By formula, area of the triangle =
bh .. (2)
substitute (1)in (2), we get
Area =
(2h-3) h
10 =
(2h-3) h
20 = 
- 20 = 0
solving the equation, we get x = 4, -2.5
The height of the triangle = 4cm
My answers C. I dunno if it's correct tho
Steps:
1. Take -x + 2y= 21
2. Add x on both sides
2y= x + 21
3. Divide everything by 2
Y= 1/2x + 10.5
4. Substitute the y in 7x + 2y= -19 for 1/2x + 10.5
7x + 2(1/2x + 10.5)= -19
5. Multiply everything in parentheses
7x + x + 21= -19
8x + 21= -19
6. Subtract 21 on both sides
7. 8x=-40
8. Divide each side be 8
9. Your answer is
X=-5
