Answer: 1. 54, 2. 48

Step-by-step explanation: To find the area of a trapezoid you add the top base and the bottom base then divide them by two, and multiply them by the height.For #1. 8+10/2= 9 then 9x6=54 For #2. 4+12/2=8 then 8 x 6=48.

Answer:

Figure it out using this: Area= 1/2(Base 1 + Base 2) x Height

Bases are the tops and bottoms of the trapezoids

Answer:

x = b-a/2

Step-by-step explanation:

2x + a = b

2x = b-a

x = b-a/2

Answer:

Step-by-step explanation:

Hello!

a)

- 11.5=  a

b)

b= -11 -7 = -18

c)

c+3 = 15

c = 15 -3 = 12

Answer:

el ancho es de 8 metros y el largo es 3 * 8 = 24 metros

width is 8 meters and length is 3*8= 24 meters

Step-by-step explanation:

Spanish

Si el ancho de la casa de la casa es x, entonces el largo de la casa es 3x.

Entonces el área = largo * ancho

área = 3x * x = 3x²

3 multiplicado por área = 9x²

9x² = (3x + 40) (x + 1)

9x² = 3x² + 3x + 40x +40

9x² = 3x² + 43x +40

0 = -6x² + 43x +40

0 = 6x²- 43x - 40

6x²- 43x - 40 = 0

Usando ecuación cuadrática

a = 6, b = -43, c- = -40

x = - b ± √b²- 4ac / 2a

x = 43 ± √1849- 4 (6) (- 40) / 12

x = 43 ± √1849 + 960/12

x = 43 ± 53/12

x = 43+ 53/12 y x = 43-53 / 12

x = 96/12 y x = -10/12

x = 8 y x = - 5/6

Ignorando el valor negativo x = 8 el ancho es de 8 metros y el largo es 3 * 8 = 24 metros

English

The length of a house is three times its width. If 40 meters are added to the length and 1 meter to the width, the area is tripled

If the width of the house of the house is x then the length of the house is 3x.

Then the area = length * breadth

area= 3x*x= 3x²

3 times area= 9x²

9x²= (3x+40 )(x+1)

9x²= 3x²+ 3x +40x +40

9x²= 3x²+ 43x  +40

0 = -6x²+ 43x  +40

0 = 6x²- 43x - 40

6x²- 43x - 40= 0

Using quadratic equation

a= 6 , b= -43 , c-= -40

x= - b±√b²- 4ac/ 2a

x= 43±√1849- 4(6)(-40)/ 12

x= 43±√1849+960/ 12

x= 43± 53/ 12

x= 43+ 53/ 12  and x= 43- 53/ 12

x= 96/ 12       and x= -10/ 12

x= 8    and x= - 5/6

Ignoring the negative value  x= 8  width is 8 meters and length is 3*8= 24 meters

Answer:

A) 79

Step-by-step explanation:

m<N = x

All angles in a triangle add up to 180 so:

x + m<L + m<M = 180

x + 32 + 69 = 180

x + 101 = 180

x = 180 - 101

x = 79

Answer:

It is (A) 79°

The summation of the triangle's angles are 180°

Step-by-step explanation:

[tex]m + l + n = 180 \\ 69 + 32 + n = 180 \\ n = 180 - 101 \\ n = 79 ^{ {} ^{.} } [/tex]

Answer:

y - 24 = - 7(x + 4)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 4, 24) and (x₂, y₂ ) = (7, - 53)

m = [tex]\frac{-53-24}{7+4}[/tex] = [tex]\frac{-77}{11}[/tex] = - 7

Using m = - 7 and (a, b) = (- 4, 24 ) , then

y - 24 = - 7(x - (- 4)), that is

y - 24 = - 7(x + 4)

Given:

EFGH is a square.

To find:

The [tex]m\angle FHG[/tex].

Solution:

We know that all interior angles of a square are right angles.

[tex]m\angle EHG=90^\circ[/tex]              (Right angle)

The diagonals of square are always the angle bisectors.

FH is a diagonal of the square. So, it bisects the angle EHG.

[tex]m\angle FHG=\dfrac{m\angle EHG}{2}[/tex]

[tex]m\angle FHG=\dfrac{90^\circ}{2}[/tex]

[tex]m\angle FHG=45^\circ[/tex]

Therefore, the measure of angle FHG is 45 degrees.

Answer:

x = 105

Step-by-step explanation:

Let the unknown (missing) number be x.

In Mathematics, quotient simply means division i.e to divide a number by another.

Thus, translating the word problem into an algebraic expression, we have;

[tex] \frac{x}{7} - 5 = 10 [/tex]

To find the value of x, we would simplify the algebraic expression.

[tex] \frac{x}{7} = 10 + 5 [/tex]

[tex] \frac{x}{7} = 15 [/tex]

Cross-multiplying, we have;

[tex] x = 15 * 7 [/tex]

x = 105

Answer:

203.28 miles

Step-by-step explanation:

Given data

charge per day= $45.95

charge per mile= 0.35

The expression for the total is

y= 45.95+0.35x

where x is the number of miles

We want to find the value of x when y= 117.10

substitute

117.10=45.95+0.35x

117.10-45.95=0.35x

71.15=0.35x

x= 71.15/0.35

x=203.28 miles

Step-by-step explanation: ANSWER : -1

f(x)=3x−1=y

⇒x=3y+1​

∴f−1(y)=3y+1​

⇒f−1(x)=3x+1​

g(x)=5x+6=z

⇒x=5z−6​

g−1(z)=5z−6​

⇒g−1(x)=5x−6​

Answer:

10/3 pizza

Step-by-step explanation:

step one:

This problem is focused on ratios and fractions

from the problem statement, Martin has 5/6 pizza

Liam has 4 times more of what Martin have

step two:

so we can express what Liam has as

=(5/6)*4 = 20/6or

=5/6+5/6+5/6+5/6= 20/6

= 20/6
