Answer: 400, 1
Step-by-step explanation:
Answer:
x² + 4x
Step-by-step explanation:
The area (A) of the base is
A = length × width
= x(4 + x) = 4x + x² = x² + 4x
Answer:
y = 3x+6
Step-by-step explanation:
y=3x-2
This is in the form
y = mx+b where m is the slope and b is the y intercept
The slope is 3 so a line parallel also has a slope of 3 since parallel lines have the same slope.
Using slope intercept form
y = 3x+b
We have a point (2,11)
11 = 3*2+b
11 =6+b
11-6 = b
5 =b
The equation is
y = 3x+6
That would be Graph C
The solution is where the 2 graphs intersect At A and B.
x + y + 2 = 0 transforms to y = -x - 2 which has slope -1 and y-intercept of -2
as in Graph C.
You can use the pythagorean theorem. Make sure that you put the measurements in the right places though. Since 11 is the measure of the hypotenuse, 11 has to be c. When you plug in the information that you have, it should look like this:
8^2 + b^2 = 11^2
Square 8 and 11.
64 + b^2 = 121
Subtract 64 from 121
121 - 64 = 57
The new equation is:
b^2 = 57
Now take the square root of both sides to get b by itself.
b = about 7.5
Answer: The height of the triangle is 7.5
