y=1 and x=4 means that in an equation/sum, if y or x are written it means they represent those numbers. if y=1 and x=4, then 4y=4=x
find x3+y2 if x=4 and y=3 ( 4*4*4)+(3*3) 64 +9 =73
First sum the terms with x: 9x + (-3)x = 6 x. Then sum the terms without x: -11 + (-13)x = -24. Then 6x - 24 =0 or x = 24/6 = 4
10 + 4 = 14 10 x 4 = 40 10 - 4 = 6 or 4 - 10 = -6 so your answer is 6 or -6
The perimeter is the distance around, the sum of the sides. A 5 x 7 or a 4 x 8 rectangle has a perimeter of 24.
the sum equals x+10
y=1 and x=4 means that in an equation/sum, if y or x are written it means they represent those numbers. if y=1 and x=4, then 4y=4=x
find x3+y2 if x=4 and y=3 ( 4*4*4)+(3*3) 64 +9 =73
2 x 50 4 x 25 5 x 20 10 x 10
First sum the terms with x: 9x + (-3)x = 6 x. Then sum the terms without x: -11 + (-13)x = -24. Then 6x - 24 =0 or x = 24/6 = 4
the cube of the sum x and 4
The product in a multiplication sum is the answer - the numbers in the question are the multiplier and the multiplicand.
-6x
x+4.
If the sum of a number and 4 is (X + 4) then twice that is 2(X + 4) which is 2X + 8
x + y = 13 x - y = 5 ------------ 2x = 18 x = 9 y = 4 Verification: 9 + 4 = 13 and 9 -4 = 5
