X=side length
6x^2 = surface area = 150
x^2 = 150/6=25
x=sqrt(25)=5
Answer:
Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.
Step-by-step explanation:
28/7 =4
7•4 is 28 or
7+7+7+7 is also 28
Answer: C
Step-by-step explanation:
Your answer is correct! When you multiply 2 matrices, the inner dimensions have to be equal. If they are equal, the resulting dimensions would be the outer dimentions.
(<u>3</u>×4)(4×<u>5</u>)
Since the inner (bolded) dimensions are the same, in this case 4×4, we know these matrices can be multiplied.
Since these matrices can be multiplied, the product will be 3×5, the underlined outer dimensions.
