What is the value of the expressions
1. 7 (3+5) = ____ + _____
2. 15 - 10 = ____ (3-2)

Answer:

There's only one answer, and that's x=0.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(3x−1)=6x−3

(3)(3x)+(3)(−1)=6x+−3(Distribute)

9x+−3=6x+−3

9x−3=6x−3

Step 2: Subtract 6x from both sides.

9x−3−6x=6x−3−6x

3x−3=−3

Step 3: Add 3 to both sides.

3x−3+3=−3+3

3x=0

Step 4: Divide both sides by 3.

x=0

Answer:

14.373 inc.sq

Step-by-step explanation:

Here's your solution

=> Area of cone = πr(r + l)

=> π = 3.14

=> radius = 1.9/2 inc

= l = 4.5 inc

=> putting value in formula

=> Area = 3.14*0.95(0.95 + 4.5)

=> Area = 2.983*5.45

=> Area of cone = 14.373 inc.sq

Answer:

2x+y+1=0

Step-by-step explanation:

this is a first degree equation with two unknown variables, x and y. they are referred to as linear equation and are typically represented in slope intercepts form, y=mx+b, where m is the slope of the line and b is the y intercept. So you want to set the equation equal to y by isolating it to one side of the equation.

Subtract all term other than y (in this case, 2x and 1) from both sides of the equation.

2x+y+1-2x-1=0-2x-1

y=-2x-1

Answer:

M=-2 & C=-1

Step-by-step explanation:

2x+y+1=0

The equation of a straight line is given as

y=mx+c

where, m is the gradient slope

c is y- intercept

from the equation 2x+y+1=0

make y subject of the formula

2x+y+1=0

y= -2x-1

Therefore, Slope (M)=-2 & y-intercept (c)=-1

Answer:

-21

Step-by-step explanation:

the formula for the perimeter of a rectangle is 2l+2w. which means twice the length and twice the width added to together.

if you mean this:

x=21+2x

minus x on both sides

0=21-x

add 21 on both sides

21=-x

x=-21

than you subsitute

2×-21=-42

-42+21= -21

The perimeter is than -21

Step-by-step explanation:

In this isosceles right triangle, the acute angles are equal and the side lengths have the ratios 1 : 1 : √2

  y° = 90° -45° = 45°

  9 : x : z = 1 : 1 : √2 = 9 : 9 : 9√2

  x = 9; z = 9√2

Answer:

  72°

Step-by-step explanation:

The external angle E is half the difference of the intercepted arcs.

Bonjour,

2x*3x =6x²

2x* -5 = -10x

-3 * 3x = -9x

-3*-5 = 15

=>

6x² -10x  - 9x +15 = 6x ² -19x  +15

Answer:

6x^2 - 19x + 15.

Step-by-step explanation:

(2x - 3)(3x -5)​

= 2x(3x - 5) - 3(3x - 5)

= 6x^2 - 10x - 9x + 15

= 6x^2 - 19x + 15.

Answer:

c = 12.5903 as it is more accurate

Step-by-step explanation:

tan65 = 27/d , value of tan65 is 2.1445

2.1445 = 27/d

d = 27/2.1445

d = 12.5903

so answer would be c as it is more accurate than others.
