Write an algebraic expression in standard form for the shaded area of the following shape

Mathematics
1 answer:
Alex Ar [27]3 years ago
3 0

Answer:

x² + 7x + 12

Step-by-step explanation:

The area of a rectangle = length × width

here length = x + 4 and width = x + 3, hence

A = (x + 4)(x + 3)

Each term in the second parenthesis is multiplied by each term in the first parenthesis.

A = x(x + 3) + 4(x + 3) ← distribute each parenthesis

A = x² + 3x + 4x + 12 ← collect like terms

A = x² + 7x + 12 ← in standard form

This is the third time I have asked this question. Someone please answer! Brainlist IF possible. Use the graph to write a linear
Likurg_2 [28]

Answer:

Use the graph to write a linear function that relates y to x. The points lie on a line. Find the slope and y-intercept of the line. Because the line crosses the y-axis at (0, −3), the y-intercept is −3.w

Step-by-step explanation:

There are three standard forms for linear functions y = f(x):

f(x) = mx + b (The "slope-intercept" form),

y - yo = m(x - x0) or, equivalently, f(x) = y0 + m(x - x0) (The "point-slope" or "Taylor" form), and.

Ax + By = C (The "general form") which defines y implicitly as a function of x as long as B 0.

Answer is 13 because the numbers are increasing though odd numbers that are also increasing if that makes sense.

It’s going from 4 > 9 > 16 > 25 > 36

so from 4-9 it adds 5 and from 9-16 it adds 7 and goes on so that’s it’s like

+5 > +7 > +9 > +11

sorry if it doesn’t make good sense

If C is between A and B, then answer the following if AB=40, AC= 2x+10, CB= 3x-5
Marat540 [252]

If C is between A and B, then, we can write the equation

AB = AC + CB


Substitute the value of AB and the expressions for AC and CB in terms of x.


40 = (2x+10)+(3x-5)


We can now solve for x.



40-10+5= 2x+3x



35=5x


Dividing by 5.


7=x


AB=40



AC=2(7)+10



AC=14+10



AC=24




BC=3(7)-5



BC=21-5


BC=16

Which relationships describe angles 1 and 2?
NikAS [45]

Supplementary angles.

This is because supplementary angles are two angles that add up to 180 degrees, and these two angles would add up to 180 degrees.
