Answer:
Addition
Step-by-step explanation:
The first step in solving 4x-3=5 is to add 3 to both sides. This demonstrates the addition property of equality, since adding a number to both sides of an equation balances it.
Answer:
q= -10
Step-by-step explanation:
1. add 3 to both sides : -q=10
2. divide by -1
3. 10 / -1 = -10
q=-10
Answer:
Step-by-step explanation:
there are 6 sides on a cube
surface area = 6 times the area of one face of the cube
= 6 times ( a side times another side) note all sides are equal
= 6(side)² is a side equal to 2/3 ?? if it is ....
= 6(2/3)²
= 6(2/3)(2/3) one of the 3s divide into 6 twice
= 2(2)(2/3)
= 2³ / 3
= 2x2x2 / 3
= 8 /3
= 2 and 2/3 units²
The square of a binomial is always a trinomail since
(a+b)^2=a^2+2ab+b^2 and so if you can write your trinomial as a^2+2ab+b^2 or a^2-2ab+b^2, it will be the square of a binomial specifically (a+b)^2 and (a-b)^2 respectively
The answer is A) -23
A is a 1x3 Matrix while B is 3x1 Matrix. Since A has the same number of rows as that of the number of columns of B, they can be multiplied. A has 1 row and B has 1 column. So, their products is a 1x1 Matrix.
Simply, the operation is:
(3)(-1) + (-2)(4) +(6)(-2) = -23
