Simplify -22 + (-5) x6

1 answer:

3 0

Ok so since we need to simplify -22+(-5)x6 let’s get started
Multiply -5 by 6
-22-30

Therefore the answer will be -52.

I’m still confused if you’re either assuming the variable x or the multiplication sign (x). So if you’re doing an algebra problem just be sure to use parentheses when you’re dealing with multiplication.

Find the value of x and the perimeter of the following shapes:

ratelena [41]

Answer:

x=2, perimeter=14

Step-by-step explanation:

Finding x

(x+1)(x+2)

x^2+2x+x+2=12

x^2+3x-10

x^2-2x+5x-10

x(x-2)5(x-2)

(x+5)(x-2)

x=-5

x=2

Length or Width should be a positve number.

x=2

Perimeter:

3+3+4+4=14

If the area of the triangle is 48 square units, what is the total area of sections 1 and 2?

MariettaO [177]

Answer:

48 square unit

Step-by-step explanation:

For a rectangle, area is given by

A=bh

Where b is base and h is height as shown in the attached diagram

For a triangle, area is given by

A∆=½bh

Given that ½bh=48

Then bh=2*48=96 square units

The overall area is 96 square units.

The area for 1&2 combined will be given by deducting the area of triangle from the overall area

Area is 96-48=48 square units

Find an equation of the line that passes through (-5,-7) and is parallel to 5x+9y+18=0. Give answer in slope intercept form

Kipish [7]

Answer:

y = - $\frac{5}{9}$ x - $\frac{88}{9}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 5x + 9y + 18 = 0 into slope- intercept form

Subtract 5x + 18 from both sides

9y = - 5x - 18 ( divide all terms by 9 )

y = - $\frac{5}{9}$ x - 2 ← in slope- intercept form

with m = - $\frac{5}{9}$

Parallel lines have equal slopes, thus

y = - $\frac{5}{9}$ x + c ← is the partial equation

To find c substitute (- 5, - 7) into the partial equation

- 7 = $\frac{25}{9}$ + c ⇒ c = - 7 - $\frac{25}{9}$ = - $\frac{88}{9}$

y = - $\frac{5}{9}$ x - $\frac{88}{9}$ ← equation of line

Could really use some help y'all-

Yuri [45]

Ok you just replace the x for a 2.

2(2)^4 - 8(2)^2 + 5(2) - 7

2(16) - 8(4) + 5(2) - 7

32 - 32 + 10 - 7

10 - 7

It's A. f(2) = 3.
