The shape of the top surface of a table is a trapezium. Find its area

qaws [65]

Answer:

0.88m²

Step-by-step explanation:

Area of a trapezium = 1/2(a+b)h

a and b are the parallel sides

h is the height

Given

a = 1m

b = 1.2m

h = 0.8m

Substitute

Area of the trapezium = 1/2(1+1.2)(0.8)

Area of the trapezium = 1/2(2.2)(0.8)

Area of the trapezium = 1.1 * 0.8

Area of the trapezium = 0.88m²

Devide (a2+ 7a+ 12)÷ (a+3)

arlik [135]

Answer:

(a - 3) • (a - 4)

Step-by-step explanation:

The first term is, a2 its coefficient is 1 .

The middle term is, -7a its coefficient is -7 .

The last term, "the constant", is +12

Multiply the coefficient of the first term by the constant 1 • 12 = 12

Find two factors of 12 whose sum equals the coefficient of the middle term, which is -7 .

-12 + -1 = -13

-6 + -2 = -8

-4 + -3 = -7 That's it

Rewrite the polynomial splitting the middle term using the two factors, -4 and -3

a2 - 4a - 3a - 12

Add up the first 2 terms, pulling out like factors :

a • (a-4)

Add up the last 2 terms, pulling out common factors :

3 • (a-4)

Add up the four terms

(a-3) • (a-4)

Really hope this helps :)

Solve for x in the equation X2-8x+41 = 0 -

djverab [1.8K]

Answer:

The value of x fro the given equation is ( 4 + 2 i ) , ( 4 - 2 i )

I.e option D

Step-by-step explanation:

Given equation as :

x² - 8 x + 41 = 0

For quadratic equation ax² + b x + c = 0

The value of x = $\frac{-b\pm \sqrt{b^{2}-4\times a\times c}}{2\times a}$

∴ For equation x² - 8 x + 41 = 0

Or, x = $\frac{8\pm \sqrt{-8^{2}-4\times 1\times 41}}{2\times 1}$

Or, x = $\frac{8\pm \sqrt{-100}}{2}$

Or, x = $\frac{8\pm 10i}{2}$

∴ x = ( 4 + 2 i ) , ( 4 - 2 i )

Hence The value of x fro the given equation is ( 4 + 2 i ) , ( 4 - 2 i )

I.e option D Answer

Leanne deposited $1,500 into a savings account for which simple interest is calculated quarterly. If her $1,500 grew to $1,509 a

Harman [31]

The answer would be B 2.4%.

After doing 9/375 = .024, you just move the decimal 2 places over to find the percentage.

Hope this helps! :)
