I believe what you're looking for is the expanded form, which would be x^2+10x. It does look like you're missing a part to the second () however.
Answer:
A = 1/2bh
b = 2cm
h will be found using the side of the triangle with Pythagoras theorem
h² + 1² = 4²
h² = 15
h = √15 cm
then,
A = <u>2</u><u>*</u><u>√</u><u>1</u><u>5</u><u> </u>
2
A = √15cm²
Answer:
Dot plot or bar graph
Step-by-step explanation:
A dot plot and bar graph would both show the exact amount of cars each day. You didn't give me any options to chose from so if these are not one of your answers, be more specific next time.
The solution to x^2 - 4x = 5 is x = -1 or 5
<h3>How to solve the equation?</h3>
The equation is given as:
x^2 - 4x = 5
Take the coefficient of x
k = -4
Divide by 2
k/2 = -2
Square both sides
(k/2)^2 = 4
Add this value to the sides of the equation
x^2 - 4x + 4= 5 + 4
Express as a difference of two squares
(x - 2)^2 = 9
Take the square root of both sides
x - 2 = ±3
Add 2 to both sides
x = 2 ± 3
Evaluate
x = -1 or 5
Hence, the solution to x^2 - 4x = 5 is x = -1 or 5

Answer:
16
Step-by-step explanation:
Because the number is closer to 16, it can be rounded off to that. 15 31/40 is the same as 15.78. When the decimal is over .50 it is rounded up to the next whole number, but when it is under .50 it si rounded down to the nearest whole number. ex. since this one is over the .50, it's rounded up, but if it were 15.36 then it would be rounded down to 15. hope this helps :D
