The first term will be an x because

x squared breaks down as x times x.

First look for factors of your constant that add to your

coefficient of the middle term in the trinomial.

Also note that the constant is negative and a negative

factors as the product of a positive and a negative.

The factors of -20 that add to -8 are -10 and +2.

So we have y = (x - 10)(x + 2).

Solve for X. 5.4 + 0.2x = 7.09 Enter your answer as a decimal or as a mixed number in simplest form in the box. x =
FromTheMoon [43]

Answer:

x = 8.45

Step-by-step explanation:

5.4 + 0.2x = 7.09

Subtract 5.4 from both sides to leave 0.2x alone

0.2x = 1.69

Divide by 0.2 on both sides to isolate x

x = 1.69/0.2

x = 8.45

A student bought a piece of hard candy that is in the shape of a sphere. The candy has a radius of 3 centimeters.
worty [1.4K]

Volume of piece candy is 113.04 cubic centimeter

<em><u>Solution:</u></em>

A student bought a piece of hard candy that is in the shape of a sphere

<em><u>The candy has a radius of 3 centimeters</u></em>

Radius = 3 cm

Use 3.14 for π

<em><u>Volume of sphere is given as:</u></em>

V = \frac{4}{3} \times \pi \times r^3

Where, "r" is the radius of sphere

<em><u>Therefore, volume of candy is given as:</u></em>

V = \frac{4}{3} \times 3.14 \times 3^3\\\\V = 4 \times 3.14 \times 3^2\\\\V = 12.56 \times 9\\\\V = 113.04

Thus volume of candy is 113.04 cubic centimeter

How would I Graph y=1/2x+2
insens350 [35]
So basically, the 2 is the y- intercept which means that is where your line starts. The 1/2 is the slope which means you make a dot every time you go up 1 and over 2

Answer:

Step-by-step explanation:

Formula

Area = B * h

Givens

Base = 2.5

height = 5.25

Solution

You choose the value for the base and height from the fact that the height touches the base (which has been extended) at right angles.

Area =  2.5 * 5.25

Area = 13.125

Answer: Area = 13.125 or 13 1/8
