Answer:
h = 2
Step-by-step explanation:
I'm assuming your periods are multiplication signs.
(h + h) X (h X h) = 16
When adding two variables like the first set of parentheses, it would become 2h. When multiplying two like variables, you add the exponents. h is the same as writing h¹. So h¹ x h¹ gives you the answer of h².
So now your equation would look like:
2h X h² = 16
As above, when you multiply two like variables you would add the exponents. Also if any number are in front of the variable you would multiply those numbers. So you have 2h¹ x 1h² and that would be 2h³. If it had been
2h¹ x 2h², your answer would have been 4h³.
But so far you have 2h¹ x 1h² = 16
2h³ = 16
Dividing both sides by 2 you get
h³ = 8
To find h you have to take the cubed root of 8. What number multiplied by itself 3 times gives you 8? 2 x 2 x 2 = 8 2 x 2 = 4 and x 2 = 8.
h = 2
If you put this into the original equation you have:
(2 + 2) x ( 2 x 2) = 16
( 4 ) x ( 4 ) = 16

Simplify ^75 select the correct answer
Answer:
to simplify the square root of 75, first I recognize that the perfect square 25 goes into it. So 75 = 25 x 3. Therefore the square root of 75 equals the square root of 25 times the square root of 3. And that means just 5 times the square root of 3.
Step-by-step explanation:
The square root of √75 is 5√3.
What is Radical?The √ symbol that is used to denote square root or nth roots. Radical Expression - A radical expression is an expression containing a square root.
A radical notation is an expression that incorporates a root, such as the square or cube root.
Given:
We have to find the square root of 75.
So, we have to factories 75 as
= 25 x 3
and, the square root of 25 is 5.
Then, √75 = √( 5 x 5 x 3)
= 5√3.

make q the subject of the formula 5(q+p)/2 = 3 + 4p
Answer:
q = [tex]\frac{6+3p}{5}[/tex]
Step-by-step explanation:
[tex]\frac{5(q+p)}{2}[/tex] = 3 + 4p ( multiply through by 2 to clear the fraction )
5(p + q) = 6 + 8p ← distribute parenthesis on left side )
5p + 5q = 6 + 8p ( subtract 5p from both sides )
5q = 6 + 3p ( divide both sides by 5 )
q = [tex]\frac{6+3p}{5}[/tex]

work out the gradient of the line y=5x-3
Answer:
The answer is 5
Step-by-step explanation:
The equation given is y=5x+3 and since the 5 is in the place of m from the general equation, 5 is the slope. Since parallel lines have the same slope, 5 is the answer. The slope is 5.
The slope is the ratio of rise to run of a line. The gradient of the line y=5x-3 is 5
How to determine the gradient of a line?The gradient of a line is also known as the slope and it is the ratio of rise to run of a line

The residence of a city voted on whether to raise property taxes the ratio of yes votes to no votes was 3 to 2 if there were 4440 total votes how many yes votes were there
Answer:
Y / N = 3 / 2
N + Y = 4440
Since Y = 3/2 N
3/2 N + N = 4440
5/2 N = 4440
N = 8880 / 5 = 1776
Y = 1776 * 3 / 2 = 2664
1776 + 2664 = 4440
2664 / 1776 = 3 / 2

A recommended portion of Lee's muesli weighs 75g.
Lee's muesli contains 71% wheat and oats, 26.5% fruit and 2.5% nuts.
a What is the mass of wheat and oats in one portion of Lee's muesli?
b What is the mass of nuts in one serving of Lee's muesli?
Answer:
Total weigh = 75g
a) so the mass of wheat and oats one protion = 75*(71/100) g = 53.25g
b) the mass of nuts in one serving = 75*(2.5/100) g = 1.875g
