La repuesta es 375,porque 3+7+5 es 15,y 15x25 es 375. Tambien el digito de las decenas es uno menos que la suma de los digitos de las centenas y de las unidades.
6.12 x 10^3 = 6120 .........<span> in standard notation

1. SUBTRACTION
inverse means opposite. The opposite of addition is SUBTRACTION.
2. 4.25x + 7 = 24
a) 4
b) 2.125
c) 7
d) 20
All these values (as shown above) are what x is like when added up together. The first one (a) is correct. The others are wrong.

Answer:
2.67 inches.
Step-by-step explanation:
Assuming that we represent the size of the squares with the letter y, such that after the squares are being cut from each corner, the rectangular length of the box that is formed can now be ( 23 - 2y), the width to be (13 - 2y) and the height be (x).
The formula for a rectangular box = L × B × W
= (23 -2y)(13-2y) (y)
= (299 - 46y - 26y + 4y²)y
= 299y - 72y² + 4y³
Now for the maximum volume:
dV/dy = 0
This implies that:
299y - 72y² + 4y³ = 299 - 144y + 12y² = 0
By using the quadratic formula; we have :

where;
a = 12; b = -144 and c = 299






Since the width is 13 inches., it can't be possible for the size of the square to be cut to be 9.33
Thus, the size of the square to be cut out from each corner to obtain the maximum volume is 2.67 inches.
I cant see numbers 2 & 3 im sorry
