Rewrite the following expression 9(6+7n)

Mathematics
1 answer:
labwork [276]1 year ago
6 0

Answer:

63n + 54

Step-by-step explanation:

9(6+7n)

First you have to multiply 6 and 9 which gives you 54. Then you’ll have to multiply 7n and 9 which equals to 63n. Whenever you see expressions like that, make sure to multiply both numbers inside the parentheses by what’s outside the parentheses. (Well, that method is mainly done like that if there’s one number outside the parentheses—like the expression you’ve provided.)

Mary is flying a kite and has let out 50 yards of kite string. Mary’s kite is directly above Erika.
ch4aika [34]

The distance of Erika from kite directly is 35.71 yards

Step-by-step explanation:

Considering the given situation as a right triangle with string as hypotenuse and the distance between both girls as base

So,

h = 50\ yards\\b = 35\ yards

As the triangle is a right triangle, we can use pythagoras theorem to solve this problem.

h^2 = b^2 + p^2\\p^2 = h^2 - b^2\\p^2 = (50)^2 - (35)^2\\p^2 = 2500-1225\\p^2 = 1275\\\sqrt{p^2} = \sqrt{1275}\\p = 35.707\ yards

Rounding off to nearest hundredth

=> 35.71 yards

Hence,

The distance of Erika from kite directly is 35.71 yards

If x² - y² = 55, and x - y = 11, then y =<br> a. 8<br> b. 5<br> c. 3<br> d. -8<br> e. -3
irina1246 [14]
X^2-y^2=55
this means that 
(x+y)(x-y)=55
we know that x-y=11 so we can write
(x+y)(11)=55
x+y=55/11 we divide by 11 and we obtain 
x+y=5

x-y=11 this means
x=y+11 we replace in the other equation (x+y=5)

y+11+y=5
2y=5-11
2y=-6
y=-3
and you find out that also 
x=8

Write an expression double 2 add 5
Aliun [14]
I am not sure, but here goes.  2 + 2 + 5  4 + 5 = 9  or double 2 is 22 + 5 = 27.

This is probably wrong.
