How do you factor this 8x^2+2x-21=0

Answers

$8x^2+2x-21=0 \n \n 8x^2+2x + 12x -12x-21=0\n\n8x^2+ 14x -12x-21=0 \n \n 2x(4x+7)-3(4x+7)=0\n\n(4x+7)(2x-3)=0$

$4x+7=0 \ \ or \ \ 2x-3 =0 \n\n4x=-7\ \ or \ \ 2x=3\n\nx=(-7)/(4)\ \ or \ \ x=(3)/(2)$

Solve it like this..
8x^2+2x-21=0
8x^2 + 14x - 12x -21=0
2x(4x+7) -3(4x+7) = 0
(4x+7)(2x - 3)=0

So factor 1 is 4x +7 =0
i.e. x=-7/4

Factor 2 is 2x -3 =0
i.e x=3/2

Find the total area the regular pyramid.

Answers

Answer:

$4+4√(10) \n72+24√(3) \n144+36√(3) \n16√(3)\n 18√(91) +54√(3) \n$

Step-by-step explanation:

The above answers are for total area. They belong to the lesson called Solid's: Pyramids. They are in order so find each T.A question and input the answer accordingly.

To find total are of a regular pyramid, we add 4 times the area of one side and the area of base.

Simplify 20 + (2 + r).

Answers

Answer:

The simplified form of given expression is 22+r.

Step-by-step explanation:

The given expression is

$20+(2+r)$

We need to find the simplified form of the given expression.

The given expression can be written as

$20+2+r$

In this expression r is variable and 20, 2 are constant terms.

Now, combine constant terms.

$(20+2)+r$

On further simplification we get

$(22)+r$

$22+r$

Therefore, the simplified form of given expression is 22+r.

First remove the parentheses because addition is commutative.
20+2+r
Add 20 and 2 together
r+22
Hope this helps.

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

f-(100/4+37)=0

Step by step solution :

STEP

Simplify ——

Equation at the end of step

f - (25 + 37) = 0

STEP

Equation at the end of step 2

f - 62 = 0

STEP

Solving a Single Variable Equation:

3.1 Solve : f-62 = 0

Add 62 to both sides of the equation :

f = 62

One solution was found :

f = 62
