alisha [4.7K]2 years ago
7 0

Answer:

a. x^{2}  + 3y^{3}

b. 3y^{3} -6

c. 5x -3

d. -6t - 5

Step-by-step explanation:

When a number has the same variable as another, you can add or subtract them

So for the first one, you can do

5x^{2} -4x^{2} = 1x^{2}  = x^{2}

(But don't forget the 3y^{3}!)

So it is:

x^{2}  + 3y^{3}

Continue this process for the rest of them

How are a desert and a tundra similar?
Hatshy [7]

Answer:

D is right option

Step-by-step explanation:

Similarities:

<em>Both the biomes experience less precipitation due to this they have a less diversity of flora and fauna as compared to other biomes like savanna, grasslands, chaparral etc. Let us see how they differ from each other!</em>

Low rain fall _ annual rainfal of lessthan 20cm in deserts, 15-20cm in tundra

Minimal life_ only small shurbs can survive in both kind of environments

Poor drainage.. In deserts, though sandy soil may seem much porous, these are most flood prone areas of world. The tundra is characterised by permafrost soils ie, under the thin layer of soil, a thick ice sheet is present and hence is no seepage.

High range of temperatures: In tundra, the maximum temperatures are recorded in summer (abt 10^C) and minimum during winter(-20 to -30^C). While, in desert too, the temperature range is high but diurnally ie, nights are too cold and day time is scorching.

Classify each polynomial by its degree and number of terms 7/4x +3
wolverine [178]

If the power of the polynomial is 1. Then the degree of the polynomial is one.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

The linear polynomial is given below.

⇒ (7/4)x + 3

The power of the polynomial is 1.

Then the degree of the polynomial is 1.

Click on all the values that satisfy this inequality x - 5 &gt; 10
JulsSmile [24]

Answer:X>15

Step-by-step explanation:

To solve an inequality like this, first of all add 5 to both sides that is, the left and side of the inequality sign and the right and side of the inequality sign (>) read as greater than. Upon adding 5 to both sides, we will have

X - 5 + 5 > 10 + 5

Then, X > 15.

Hence values that satisfies the given inequality are numbers greater than 15 such as 16, 17, 18,...

Find the volume of a cylinder with a diameter of 8 inches and a height that is three times the radius use 3.14 for pie and round
nexus9112 [7]

The volume of the cylinder is 602.88 \ in^3

Explanation:

The diameter of the cylinder is 8 in

The radius of the cylinder can be determined using the formula,

r=\frac{d}{2}

Substituting d=8 , we have,

r=\frac{8}{2}=4

Thus, the radius of the cylinder = 4 in

It is given that the height is three times the radius.

Thus,

h=3r\\h=3(4)\\h=12 \ in

Thus, the height of the cylinder is 12 in

The formula to find the volume of the cylinder is given by

V=\pi r^{2} h

Substituting the values in the formula, we have,

V=\pi (4)^{2} (12)\\V=(3.14)(16)(12)\\V=602.88 \ in^3

Thus, the volume of the cylinder is 602.88 \ in^3
