Can someone find the factors of this equation I’ll mark u as brainlist

Answers

Answer 1

Answer:

x = -4 , x = -1

Step-by-step explanation:

x² + 5x + 4 = 0

1) write 5x as a sum

x² + 4x + x + 4 = 0

2) factor out x from the expression

x ( x + 4 ) + x + 4 = 0

3) factor out x + 4 from the expression

( x + 4 )( x + 1 ) = 0

4) the product of factors equals to 0

i) x + 4 = 0

x = -4

ii) x + 1 = 0

x = -1

Answers

Answer:

Even if a right solid became oblique, the volume would not change, because the cross sectional area and height would remain the same. Therefore, by Cavalieri's principle, the volume is the same as the original solid.

Answer: D. 2

Step-by-step explanation:

-3t + 6 = 0

1. Subtract 6 from each side

-3t + 6 - 6 = 0 - 6

-3t = -6

2. Divide each side by -3 to isolate t and get the answer to the equation

-3t/-3 = -6/-3

t = 2

You can check your answer by plugging your calculated value back into the equation and evaluating to find that 0 = 0.

Find the value of d that makes the equation true.

Answers

Answer:

The value of d that balances the equation is d=15

Step-by-step explanation:

Equations

We are given an image with a hanger that represents a balanced equation.

If the equation is balanced, then the 'weights' of each side should be equal.

On the right side, there is 21 and on the left side, there are 6 and d.

Adding both, we have 6+d on the left side.

Equating both sides:

6 + d = 21

To find d, we subtract 6 on both sides:

d = 21 - 6

d = 15

The value of d that balances the equation is d=15

Answer:

d=15

Step-by-step explanation:

6+d=21

so that means d=15

6+15=21

3 balloon + 2 cakes = £19
9 balloon + 3 cakes = £42

work out:
1 balloon in £
1 cake in £

Answers

Step-by-step explanation:

3 balloons + 2 cakes = £19

=> 9 balloons + 6 cakes = £57 (multiply by 3)

9 balloons + 6 cakes = £57

- (9 balloons + 3 cakes = £42)

=> 3 cakes = £15, 1 cake = £5.

Therefore 3 balloons + 2(£5) = £19,

3 balloons = £9, 1 balloon = £3.

Hence each balloon is £3 and each cake is £5.

How many solutions are there to the following equation?
5 ( x-3 ) - 3x = 8x - 15 - 6x

A) exactly two solutions
B) exactly one solution
C) no solution
D) infinitely many solutions

Answers

Answer:

D) infinitely many solutions

Step-by-step explanation:

5 ( x-3 ) - 3x = 8x - 15 - 6x

5x - 3x - 15 = 8x - 6x - 15

2x - 15 = 2x - 15

2x = 2x

Since, equations of both lines are same. Therefore, there are infinitely many solutions.

Answer:

Step-by-step explanation:

Given

5(x - 3) - 3x = 8x - 15 - 6x

5x - 15 - 3x = 2x - 15

2x - 15 = 2x - 15

Since both sides are the same then any real value of x will be a solution.

That is there are infinitely many solutions

What is the slope of the linear equation y=x+10
a. Slope=m=10
b. Slope=m=1
c. Slope=m=5
d. Slope=m=11

Answers

Answer:

slope = 1

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 )

y = x + 10 ← is in slope- intercept form

with slope m = 1

The answer is A because slope=m=10 is equal to a line

Answers

Answer:

x = 14[tex]\sqrt{2}[/tex]

y = 14

z= 14[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Notice that the top triangle is a 45-45-90 triangle and the triangle below is a 30-60-90 triangle.

Using the fact that the top triangle is a 45-45-90 triangle and also an isosceles triangle, we can see that x will be the same as its respective leg, 14[tex]\sqrt{2}[/tex]

Now, we must find a side length of the bottom triangle. We can use the Pythagorean Theorem to find the third side of the top triangle, which is also a side of the bottom triangle. We can find that the third side must be 28. We can now use this to find the other sides of the bottom triangle.

Since y is opposite to the 30 degree angle, it is half of the hypotenuse. The hypotenuse which we found earlier is 28, therefore, y is 14. z is then 14[tex]\sqrt{3}[/tex] using either Pythagorean Theorem or special right triangle properties for 30-60-90.

Step-by-step explanation:

Wilson is 6 years older than Mary.

(MARY's age + 6 = WILSON's age)

Wilson's age is 10 years less than five times Mary's age.

(MARY's age * 5 - 10years = WILSON's age)

(Mary is 4 years old and Wilson is 10:

4 + 6 = 10

4(5) = 20 - 10 = 10
