Hey don't cry . I'm not good at math either but try to take a deep breath.
Answer:
23
Step-by-step explanation:
The sides of a square are all the same length, so if 3 of them total 48, one of them must be 48/3 = 16.
If the length of the rectangle is 7 longer than the side of the square, it is
... 16 + 7 = 23
IM going to assume that the "2" is to be squared. If so, then the answer is 2(15x^2+8)
Answer:
64
Step-by-step explanation:
First of all substitute the values to where ever you see their corresponding variables to make them multiply.
x = 9
y = 3
z = 2
so we get
8x as 8(9),
7z as 7(2)
2y as 2(3)
then the it's will be
8(9) - 7(2) + 2(3)
which is
72 - 14 + 6
finally we get
64
B) 2 (5 + 7) = 2 × 5 + 2 × 7
Distributing the two multiples the five and seven and adds there them together.
