Answer:
20cm
Step-by-step explanation:
Given data
Area= 80cm^2
we know that the expression for the area of a triangle is
A= 1/2B*H
from the given expression 1/2(8h) =80 the base is 8cm
let us substitute to find the height h
1/2(8h) =80
4h=80
h= 80/4
h= 20cm
Hence the heigth h is 20cm
E) (x-2)(x-1)
substitute x = 0
= (0-2)(0-1)
= (-2)(-1)
= 2
f)2x(3x+2)
Substitute x = 10
2*10(3(10)+2)
= 20(30+2)
= 20(32)
= 640
Hope this helps!
Answer:
X=1
Step-by-step explanation:
1. Since y equals both 2x+5 and 4x+5, you can substitute 2x+5 for y into the first equation.
2. You then have 2x+5=4x+3
3. Then, solve the equation
4. 5=2x+3 (Subtract 2x from both sides)
5. 2=2x (Subtract 3 from both sides)
6. x=1 (Divide both sides by 2)
