Answer:

$28+((24/(8-2^{2} ))*7)$

Step-by-step explanation:

After placing parentheses

$28+((24/(8-2^{2} ))*7)$

⇒

$28+((24/(8-2^{2} ))*7)\\=28+((24/(8-4 ))*7\\=28+((24/4 ))*7\\=28+((6))*7\\=28+42\\=70$

MA_775_DIABLO [31]

Answer: $A^{-1}=\left[\begin{array}{cc}\frac{3}{2}&-\frac{1}{2}\\-2&1\end{array}\right]$

<u>Step-by-step explanation:</u>

$\left[\begin{array}{cc}2&1\\4&3\end{array}\right]=\left[\begin{array}{cc}1&0\\0&1\end{array}\right]$

$\dfrac{1}{2}Row\ 1\rightarrow\left[\begin{array}{cc}1&\frac{1}{2}\\4&3\end{array}\right]=\left[\begin{array}{cc}\frac{1}{2}&0\\0&1\end{array}\right]$

$Row\ 2 -4 \ Row\ 1\rightarrow \left[\begin{array}{cc}1&\frac{1}{2}\\0&1\end{array}\right]=\left[\begin{array}{cc}\frac{1}{2}&0\\-2&1\end{array}\right]$

$Row\ 1-\dfrac{1}{2}\ Row\ 2 \rightarrow \left[\begin{array}{cc}1&0\\0&1\end{array}\right]=\left[\begin{array}{cc}\frac{3}{2}&-\frac{1}{2}\\-2&1\end{array}\right]$

a trapezoid with an area of 166.75 in has bases that measure 21in and 8 in find the height of the trapezoid

alisha [4.7K]

Answer:

height = 11.5 in

Step-by-step explanation:

The area (A) of a trapezoid is calculated using the formula

A = $\frac{1}{2}$ h(a + b)

where h is the height and a, b the bases

here a = 21, b = 8 and A = 166.75, hence

$\frac{1}{2}$ h(21 + 8) = 166.75

Multiply both sides by 2 to eliminate the fraction

29h = 333.5 ( divide both sides by 29 )

h = 11.5 in

Can someone pls pls PLS, help me out? ASAP!! (Geometry)<br> “Complete the proof”

Maru [420]

1) $\overline{AB} \perp \overline{BD}$ , $\overline{AB} \cong \overline{DB}$ , $\overline{AC} \cong \overline{DE}$ (given)

2) $\angle ABD$ is a right angle (perpendicular lines form right angles)

3) $\triangle ABD$ and $\triangle DEB$ are right triangles (a triangle with a right angle is a right angle)

4) $\triangle ABD \cong \triangle DEB$ (HL)

5) $\angle ACB \cong \angle DEB$ (CPCTC)
