Answer:
The common difference is 2
Step-by-step explanation:
The formula for an arithmetic sequence is
an = a1+d(n-1)
a1 = -5
a10 = 13
Substituting n=10 a10=13 and a1 =-5
13 = -5 +d (10-1)
13 = -5 +9d
Add 5 to each side
13+5 = -5+5 +9d
18 = 9d
Divide each side by 9
18/9 = 9d/9
2 =d
Answer:
<h2>2x^3+3x^2</h2>
Step-by-step explanation:
<h3>x^2(2x+3)</h3><h3 /><h3>=(x^2)(2x+3)</h3><h3 /><h3>=(x^2)(2x)+(x^2)(3)</h3><h3 /><h3>=2x^3+3x^2</h3>
29.87 should be it hopefully
If you reduce them by 12 you'll get
If that's what you're asking
The area of a triangle can be calculated using the following equation:
A = 1/2 (B x H)
Where B is the dimension of the base and H is the height of the triangle.
Since the area is known and the dimension of the base is also known, substitute the values into the equation to find the height:
3.6 cm2 = 1/2 (6 cm) (H)
Solving yields an answer of 1.2 cm. Hence the height is 1.2 cm.
