What is the best estimate for the sum of 3/8 and 1/12

WARRIOR [948]

Have you never added fractions

3/8 + 1/12

you have to make the denominators even, so 24 is divisible by both

there for you make the denominators 24 and multiply the numerator by how many times the denominator had to be multiplied. so...

9/24 + 2/24

add them up and you get

11/24

Thats your answer

Isoke is solving the quadratic equation by completing the square.10x2 + 40x – 13 = 0 10x2 + 40x = 13 A(x2 + 4x) = 13What is the

Elina [12.6K]

we have

$10x^{2} + 40x - 13 = 0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$10x^{2} + 40x =13$

Factor the leading coefficient

$10(x^{2} + 4x) =13$ ----------> the value of A is $10$

Complete the square. Remember to balance the equation by adding the same constants to each side

$10(x^{2} + 4x+4) =13+40$

$10(x^{2} + 4x+4) =53$

Rewrite as perfect squares

$10(x+2)^{2} =53$

$10(x+2)^{2} =53 \\ (x+2)^{2} =\frac{53}{10} \\ \\ x+2=(+/-)\sqrt{\frac{53}{10}} \\ \\ x1=-2+\sqrt{\frac{53}{10}}\\ \\ x2=-2-\sqrt{\frac{53}{10}}$

therefore

the answer is

the value of A is $10$

Find the area of a trapezoid with a base of 21.6 m, a height of 4.5 m, and top of 11.9 m. Round your answer to the nearest hundr

Serga [27]

Answer:

$A=75.37\ m^2$

Step-by-step explanation:

Given that,

The base of a trapezoid, b = 21.6 m

Height of the trapezoid, h = 4.5 m

The tope of the trapezoid, a = 11.9 m

We need to find the area of a trapezoid. The formula for the area of a trapezoid can be given by :

$A=\dfrac{1}{2}\times (sum\ of\ parallel\ sides)\times height$

Put all the values,

$A=\dfrac{1}{2}\times (21.6+11.9)\times 4.5\\\\=75.37\ m^2$

Hence, the area of a trapezoid is equal to $75.37\ m^2$ .

Subtract -5x^2-9x+8−5x <br> 2<br> −9x+8 from -6x^2+5−6x <br> 2<br> +5.

Lemur [1.5K]

Answer:

−10x2+−18x+26

Step-by-step explanation:

Let's simplify step-by-step.

−5x2−9x+8−5x2−9x+8−−6x2+5−6x2+5

=−5x2+−9x+8+−5x2+−9x+8+6x2+5+−6x2+5

Combine Like Terms:

=−5x2+−9x+8+−5x2+−9x+8+6x2+5+−6x2+5

=(−5x2+−5x2+6x2+−6x2)+(−9x+−9x)+(8+8+5+5)
