Answer:

34.5 square meters

Step-by-step explanation:

We assume you want to find the area of the shaded region. (The actual question is not visible here.)

The area of the triangle (including the rectangle) is given by the formula ...

A = 1/2bh

The figure shows the base of the triangle is 11 m, and the height is 1+5+3 = 9 m. So, the triangle area is ...

A = (1/2)(11 m)(9 m) = 49.5 m^2

The rectangle area is the product of its length and width:

A = LW

The figure shows the rectangle is 5 m high and 3 m wide, so its area is ...

A = (5 m)(3 m) = 15 m^2

The shaded area is the difference between the triangle area and the rectangle area:

shaded area = 49.5 m^2 - 15 m^2 = 34.5 m^2

The shaded region has an area of 34.5 square meters.

Answer:

$t=\frac{1}{2}$

Step-by-step explanation:

We want to solve for the value of t in the equation

$4(t+\frac{1}{4})=3$

Since we are trying to make t the subject of the formula (or isolate t)

Divide both sides by 4

$\dfrac{4(t+\frac{1}{4})}{4} =\dfrac{3}{4}$

This gives us:

$t+\frac{1}{4} =\frac{3}{4}$

Next, we subtract $\dfrac{1}{4}$ from both sides

$t+\frac{1}{4}-\frac{1}{4} =\frac{3}{4}-\frac{1}{4}\\t=\dfrac{3-1}{4}=\frac{2}{4}=\frac{1}{2}\\t=\frac{1}{2}$

Step-by-step explanation:

The advantages of writing the polynomial expression

-7 $x^{2}$ + 32x + 240 in factored form when interpreting this

situation

Factorizing the quadratic equation gives

-7 $x^{2}$ + 32x + 240

-7 $x^{2}$ +60x - 28x + 240

x×(-7x + 60) -4 ×(-7x + 60)

(x-4)×(-7x + 60)

The roots of the equation 4,-60/7

Advantages of writing the polynomial expression in factored

we directly know the roots

we can easily draw the graph of the quadratic

A horizontal line contains points A, C, B. 2 lines extend from point C. A line extends to point E and another line extends to po

Effectus [21]

Answer:

Option (2).

Step-by-step explanation:

In the figure attached,

A, C and B are the points lying on a straight line.

2 lines EC and DC have been drawn by extending the lines from C to E and D respectively.

Ray CE is the angle bisector of ∠ACD.

That means CE divides ∠ACD in two equal parts.

m∠ACE = m∠DCE

Since m∠ACD = m∠ACE + m∠DCE

= 2(m∠ACE)

m∠ACE = $\frac{1}{2}(\angle ACD)$

Therefore, option (2) will be the answer.

-2(x - 2) - 4x = 3(x + 1) - 9x

Sonbull [250]

$\huge\boxed{\text{no solution}}$

Distribute the $-2$ and the $3$ . $-2x-2(-2)-4x=3x+3(1)-9x$

Multiply. $-2x+4-4x=3x+3-9x$

Combine the like terms. $-6x+4=-6x+3$

Add $6x$ on both sides of the equation. $4=3$

This statement is false, so this equation has $\boxed{\text{no solution}}$ .
