Answer: A = (b²-5b)/2
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Base =b
Height = h = b-5 (the height is 5 units shorter than the base)
Since:
Area of a triangle (A)= (base x height) ÷ 2
Replacing with the values given:
A = [b (b-5)] ÷2
A = (b²-5b)/2

Answer:
(x+1) ( x+(1/2))
Step-by-step explanation:
6x² +9x +3 , divide all terms by 6 to have the first term with coefficient 1
x² + (9/6)x + (3/6) , simplify the fractions
x² + (3/2)x + (1/2)
To get x² the first term we should have
(x.....)(x.....)
To get the last term (1/2) we should have
(x...1)(x...(1/2))
To get the middle term (3/2)x we should have
+1*x +(1/2) x = (2/2)x +(1/2)x = (3/2)x
(x+1) ( x+(1/2))
Answer:
1, 000
Step-by-step explanation:
2% · <em>x</em> = 20
0.02 · <em>x</em> = 20
20/0.02 = <em>x</em>
<em>x</em> = 1000
Double-Check:
1000 · 0.02 = 20
