What is the missing expression? x 8 + 3x 5 = x5(_____)

2 answers:

6 0

The missing expression is clearly a part of the factored polynomial.

We have to factor the polynomial.

x⁸+3x⁵

Find the GCF between 1,3,x,5,8

The GCF is x⁵

Divide the polynomial by x⁵

x⁵(x³+3)

I'm assuming that x 8 = x⁸ and 3x 5 = 3x⁵.

So let's solve.

x⁸ + 3x⁵ = x⁵(____)
x⁸ + 3x⁵ = x⁵(x³ __)
x⁸ + 3x⁵ = x⁵(x³ + 3)

Therefore the missing expression is (x³ + 3)

Answer:

D) x = √5

Step-by-step explanation:

$\sqrt{x^{2}+4 }-1 = 2$

$\sqrt{x^{2}+4 } = 3$

$x^{2}+4 = 3^{2}$

$x^{2}+4 = 9$

$x^{2} = 9 -4$

$+x = \sqrt{5} , -x = \sqrt{5}$

joy added 26 new contacts to her phone list. She now has a total of 100 contacts. Let c represent how many contacts joy had on h

Nesterboy [21]

Answer: 26 + c = 100

Step-by-step explanation: To find what c equals, we must flip the solution around and subtract it. When we take 100 - 26, we get 74. Therefore, c = 74. I hope this helped! :)

Find the area of the triangle belowunits given are cm, cm^2, cm^3

zloy xaker [14]

Answer:

$A_T=150cm^2$

Explanation: We need to find the area of the triangle, We know that the area of any right triangle is:

$A_T=\frac{1}{2}(b\times h)$

Therefore in the information given we have the following:

$\begin{gathered} h=20\operatorname{cm} \\ b=15\operatorname{cm} \end{gathered}$

Therefore the Area of this triangle is as follows:

$\begin{gathered} A_T=\frac{1}{2}(b\times h) \\ \therefore\rightarrow \\ A_T=\frac{1}{2}(20cm\times15cm)=\frac{1}{2}(20\times15)cm^2 \\ A_T=\frac{1}{2}(300)cm^2=150cm^2 \\ \therefore\rightarrow \\ A_T=150cm^2 \end{gathered}$

Note! Units are centimeter-squared
