1.4.
calculate the value of each expression for the given number values:
+ 3y – y + 5 if y = -1
(3x?y-3)2 if x = 2 and y = -1
If a = -2, b = 1 and c = 0, calculate the value of:
(a + b) + (a + b + c)(a - b)
2.1 25-3a2b2 + (3,5)
1.1 x2 - 3x + 4 if x = -2
1.3 (37) if a = 2 and b = -1

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
