Answer:
9
Step-by-step explanation:
just do 16 - 5 its exactly the same
Answer:
Simplification
x(y+4)+3(2x+7y) = xy + 10x + 21y
= x(y + 10) + 21y
On evaluation when x=5 and y=6,
The expression is equal to 206
Step-by-step explanation:
Note that x and y are unknown variables.
On expansion,
x(y+4)+3(2x+7y)
= xXy + xX4 + 3X2x + 3X7y
= xy + 4x + 6x + 21y
= xy + 10x + 21y
On factorising,
xy + 10x + 21y = x(y + 10) + 21y
Evaluation when x=5 and y = 6
We substitute the given values of x and y into the simplified expression
xy + 10x + 21y
= 5X6 + 10X5 + 21X6
= 30 + 50 + 126
= 206
Therefore, on evaluation of the given expression, when x=5 and y=6, we get 206
Answer:
20% tip.
Step-by-step explanation:
4.5/22.5=.2
Tip=0.2
It will be y+3y and the answer is 4y
Well...
The word reflection (in general) is the mirror image of something
Geometry refers to the study of shapes
Therefore, the geometric term "reflection" is <em>a mirror image of a shape.</em>
