Answer: No it is not. The correct answer is 100. The little two indicates that 10 is being squared which means you multiply 10 by itself. Ex. 10x10=100

Hope this helps!

How do i find the slope of 5x-12y=24??
Aloiza [94]
Rearrange into the form y = mx + c

m will be the gradient

5x - 12y = 24

-12y = 24 - 5x

y = (24/-12) - (5/-12)x

y = -2 + (5/12) x

m=5/12

so the gradient is 5/12

Answer:

a   x sqrt(7) - 49sqrt(x)

Step-by-step explanation:

sqrt(7x) [ sqrt(x) - 7sqrt(7)]

Distribute

sqrt(7x) *sqrt(x) - sqrt(7x)*7sqrt(7)

We know that sqrt(a) sqrt(b)= sqrt(ab)

sqrt(7x^2)  - 7sqrt(7^2 *x)

Now lets separate out the perfect squares

sqrt(7) *sqrt(x^2) - 7sqrt(7^2)*sqrt(x)

x sqrt(7) - 7*7sqrt(x)

x sqrt(7) - 49sqrt(x)

an architect created plans for a house using a scale factor of 1:16 . In the plans, the floor of the house has an area of 7 squa
Yuki888 [10]
To figure this out you would need to create a rectangle with dimensions that give you an area of 7 ft.². The easiest example would be a rectangle that is one by seven. If the scale is 1:16, that means for every foot it is actually representing 16 feet. The actual length and width would be found by multiplying 1×16 and 7×16. The true dimensions then would be 16 x 112. Multiply this together to get a total area of 1792 ft.².
