Answer:

13(x)⁴ + 7(x)²-6(x) + 7

Explanation:

$\hookrightarrow \sf (6x^4 -2x^3+7x^2-x)+(7x^4+2x^3-5x+7)$

remove the parenthesis

$\sf \hookrightarrow 6x^4-2x^3+7x^2-x+7x^4+2x^3-5x+7$

group the variables

$\hookrightarrow \sf 6x^4+7x^4-2x^3+2x^3+7x^2-x-5x+7$

add similar terms

$\sf \hookrightarrow 13x^4+7x^2-x-5x+7$

simplify

$\hookrightarrow \sf 13x^4+7x^2-6x+7$

$\qquad\qquad\huge\underline{{\sf Answer}}$

Let's solve ~

$\qquad \tt \dashrightarrow \:\tt(6x {}^{4} −2x {}^{3} +7x {}^{2} −x) + ( 7x {}^{4} + 2x {}^{3} −5x + 7)$

$\qquad \tt \dashrightarrow \:\tt6x {}^{4} −2x {}^{3} +7x {}^{2} −x + 7x {}^{4} + 2x {}^{3} −5x + 7$

Now, move all like terms aside :

$\qquad \tt \dashrightarrow \:6 {x}^{4} + 7 {}x^{4} - 2 {x}^{3} + 2 {x}^{3} + 7 {x}^{2} - x - 5x + 7$

Add the like terms ~

$\qquad \tt \dashrightarrow \:13 {}x^{4} + 7 {x}^{2} + 6x + 7$

Write 3/5 as a division

ollegr [7]

Answer:

3/5 as a division is 0.6

Step-by-step explanation:

To write a fraction as a division, we basically divide the values, since the fraction represents a division.

In this question:

We want 3 divided by 5.

3 is less than 5, so we can multiply 3 by 10(getting 30), and adding a 0 to the quotient.

So now 0.(30/5) = 0.6, which means that 3/5 as a division is 0.6.

A triangle with two vertices located at (5, −8) and (5, 4) has an area of 48 square units. Determine one possible location of th

RoseWind [281]

Answer:x=1.5

Step-by-step explanation:

Given

Two points co-ordinates are given

A=(5,-8)

B=(5,4)

let other point be C =(x,y)

Area of triangle is given by

$A=\begin{vmatrix}5& -8&1\\5& 4&1\\x& y&1\end{vmatrix}$

$A=5\left ( 4-y\right )+8\left ( 5-x\right )+1\left ( 5y-4x\right )$

A=20-5y+40-8x+5y-4x

A=60-8x

and A=48 square unit

48=60-8x

x=1.5

As area is independent of y therefore at x=1.5 any value of y will give area of 48 square unit

An isosceles triangle always has three interior angles that measure 60° each.

Nataly [62]

Answer:

False

Step-by-step explanation:

The definition given is that of an equilateral triangle, NOT that of an isosceles triangle. An isosceles triangle has at least two angles that are equal by definiton. They need not be 60 degrees. For example, a triangle with angle measures of 140, 20, and 20 is an isosceles triangle because two of the angles are equal. Hope this helped!
