Answer:
d. 64
Step-by-step explanation:
x^2+16x
The coefficient of the x term is 16
Divide by 2
16/2 =8
Then square it
8^2 = 64
We add 64
x^2 +16x +64
(x+8)^2
I'm not sure what the <span>879-06-03-00-00-con_files/i0040000.jpg stands for but I'll just solve the given choices and you can choose which is the correct one.
1 inch = 2.54 cm
a) 88.90 cm * 1inch / 2.54 cm = 35 inches </span>→ 35 inches = 88.90 cm . I THINK THIS IS THE CORRECT ANSWER TO YOUR QUESTION.<span>
b) 77.00 cm * 1inch / 2.54 cm = 30.31 inches </span><span>
c) </span><span>13.78 cm * 1inch / 2.54 cm = 5.43 inches
d.) 21.74 cm * 1inch / 2.54 cm = 8.56 inches</span>
Answer:
Step-by-step explanation:
1. Create an equation
<em><u>Concept</u></em> :
If x = 5, then subtracting 5 from both sides gives you x - 5 = 0. Do this to both variables
If x - 5 = 0 and y - 12 = 0, those two statements equal the same thing. So
2. Add 5 to both sides to isolate variable X
3. (Optional) Plug given values into new equation to check answers
5 = 5 is a true statement
Answer:
Answer:The formula for the area of a parallelogram is A = bh, and the formula for area of a triangle is A = 1/2bh. Since a triangle is half of the area of a parallelogram with the same base and height, the only difference in the formula is 1/2.
Step-by-step explanation:
Answer:
x = 101/20, y = 1/4
Step-by-step explanation:
Solve the following system:
{-y + 5 x = 25 | (equation 1)
3 y + 5 x - 1 = 25 | (equation 2)
Express the system in standard form:
{5 x - y = 25 | (equation 1)
5 x + 3 y = 26 | (equation 2)
Subtract equation 1 from equation 2:
{5 x - y = 25 | (equation 1)
0 x+4 y = 1 | (equation 2)
Divide equation 2 by 4:
{5 x - y = 25 | (equation 1)
0 x+y = 1/4 | (equation 2)
Add equation 2 to equation 1:
{5 x+0 y = 101/4 | (equation 1)
0 x+y = 1/4 | (equation 2)
Divide equation 1 by 5:
{x+0 y = 101/20 | (equation 1)
0 x+y = 1/4 | (equation 2)
Collect results:
Answer: {x = 101/20, y = 1/4
