Answer:

64 square units

Step-by-step explanation:

Split the figure into 2 rectangles of dimensions:

4 × 10

8 × 3

And solve.

(4 × 10) + (8 × 3) = 40 + 24 = 64 square units

See the attached image for a model.

Elanso [62]

Answer:

The measure of angle BCD is $68.5\°$

Step-by-step explanation:

step 1

Find the value of x

we know that

$m$ -----> form a straight line

substitute the values

$(3x+4)\°+(6x-8)\°+(7x-20)\°=180\°$

$(16x-24)\°=180\°$

$16x=180\°+24\°$

$16x=204\°$

$x=12.75\°$

step 2

Find the measure of angle BCD

$m$

substitute the value of x

$m$

191.2=2.3L+65.5 helppppppppppppppppppppppppppp

svetlana [45]

Answer:

Step-by-step explanation:

191.2 = 2.3L +65.5

191.2 - 65.5 = 2.3L {Subtract 65.5 from both sides}

125.7= 2.3L

L = 125.7/2.3

L = 54.65

Answer:

If, a = 2 and b = 3

It's not equivalent.

<h3>Diego</h3><h3> $4a + 9b = 7a + 5b - 3a + 4b \\ 4(2) + 9(3) = 7(2) + 5(3) - 3(2) + 4(3) \\ 8 + 27 = 14 + 15 - 6 + 12 \\ 35 = 35 \\$ </h3>

It's equivalent.

The correct equation is 4a + 9b.

$\text{ if } \Delta=0\text{ then there is one x-intercept : }x=-\dfrac{b}{2a}\\\\
\text{ if } \Delta\ \textless \ 0\text{ then there are no x-intercept : } x=\varnothing\\\\
\text{ if } \Delta>0\text{ then there are two x-intercept : }x_1,x_2=\dfrac{-b\pm\sqrt{\Delta}}{2a}\\\\$
