2x^2 + ax = x(2x+ 7)
2x^2 + ax = 2x^2 + 7x
Subtract 2x^2 from both sides
ax = 7x
a = 7
Answer:
3 13/15
Step-by-step explanation:
This is just addition so easy
P.S.
Why did you put ur face in so weird
the total area of the figure A = 144.5 cm²
<h3>
How to find the area?</h3>
First, the area of a rectangle of length L and width W is:
A = W*L
Here we have:
L = 13cm
W = 9cm
Then the area is:
A = 9cm*13cm = 117 cm²
For a triangle of height H and base B, the area is:
A = B*H/2
Here the base measures 11cm, and the height is:
H = 13cm - 8cm = 5cm
So the area of the triangle is:
A= 5cm*11cm/2 = 27.5cm²
Then the total area of the figure is:
area = 27.5cm² + 117 cm² = 144.5 cm²

Answer:
Step-by-step explanation:
Given that,
The arithmetic sequence is :
-28,-13,2
First term = -28
Common difference = -13-(-28) = 15
We need to find the 64th term of the sequence. The nth term of the sequence is given by :
Put all the values,
So, the 64th term of the sequence is equal to 917.
