The area of the trapezoid

ELEN [110]

Answer:

Step-by-step explanation:

The formula of an area of a trapezoid:

$A=\dfrac{b_1+b_2}{2}\cdot h$

b₁, b₂ - bases

h - height

We have b₁ = 10in, b₂ = 5in and h = 11in. Substitute:

$A=\dfrac{10+5}{2}\cdot11=\dfrac{15}{2}\cdot11=7.5\cdot11=82.5\ in^2$

What is the simplified form of ?

Natalija [7]

Let's set it up like this:
$\frac{\frac{x}{3}-\frac{y}{4}}{\frac{x}{4}+\frac{y}{3}}$
Find the LCD, which is 12, and adjust them according to that.
$=\frac{\frac{4x-3y}{12}}{\frac{3x+4y}{12}}$
Divide.
$=\frac{\left(4x-3y\right)\cdot \:12}{12\left(3x+4y\right)}$
Cancel the common factor, which is 12.
$=\frac{4x-3y}{3x+4y}$
That would be our answer!

Let me know if you have any questions regarding this problem!
Thanks!

I have this question and I need it done bad... Help please? Picture included I was never taught matrix

____ [38]

Multiply the numbers on the major axis which are 2 and -9 to get -18. Subtract from that 3*4 = 12. So -18-12 = -30. That's the determinant.
