Write the quadratic equation in standard form:

djyliett [7]

Answer:

-4x^2+7x +6

Step-by-step explanation:

-7x + x^2 = - 3x^2 + 6

Subtract x^2 from each side

-7x + x^2-x^2 = - 3x^2-x^2 + 6

-7x =-4x^2 +6

Add 7x to each side

-7x+7x =-4x^2+7x +6

0= -4x^2+7x +6

The standard form is Ax^2 +Bx +C

Priya bought x grams of flour Clara bought 3/8 more than that select all questions that represent the relationship between the a

timama [110]

Answer:

Option C : $x+\frac{3}{8}x$ is the correct answer.

Step-by-step explanation:

Given that:

Quantity of flour bought by Priya = x grams

Quantity of flour bought by Clara = 3/8 more than that

It means that Clara bought the amount bought by Priya plus an additional 3/8 of flour that was bought by Priya

Total bought = y

y = x + $\frac{3}{8}x$

Hence,

Option C : $x+\frac{3}{8}x$ is the correct answer.

FURNITURE A modern table is constructed with four legs made

Troyanec [42]

The volume of a shape is the amount of space in it.

The expression that represents the volume of one table leg is: $V = l^3 + n^3$
The sides of the legs is 14.37 inches long

<u>(a) The volume of one table leg</u>

Represent the side length of the leg with l, and the side length of the notch with n.

So, the expression that represents the volume of one table leg is:

$V = l^3 + n^3$

<u>(b) The length of the sides</u>

From the question, we have:

$n = 40\% \times l$

Express 40% as decimal

$n = 0.40 \times l$

$n = 0.4l$

Substitute 0.4l for n in $V = l^3 + n^3$

$V =l^3 + (0.4l)^3$

$V =l^3 + 0.064l^3$

$V =1.064l^3$

The volume of the 4 legs is given as: 12636

So, the volume of one leg would be 12636/4

So, we have:

$1.064l^3 = \frac{12636}{4}$

$1.064l^3 = 3159$

Divide both sides by 1.064

$l^3 = 2968.985$

Take cube roots of both sides

$l = 14.37$

Hence, the sides of the legs is 14.37 inches long
