Answer: $840
Step-by-step explanation:
- Set up the proportion 210/10 = x/40.
- To solve it quickly, multiply 210 with 4, since 10*4 = 40. Therefore, x = 840.
Answer:
A
Step-by-step explanation:
Answer:
(x-2)(x - 3)(x - 5)
(x - 2)(x-3)(x - 5)(x + 5)
(x + 2)(x + 3)(x + 5)
(x + 2)(x+3)(x - 5)
Answer:a rectangular array of quantities or expressions in rows and columns that is treated as a single entity and manipulated according to particular rules.
Step-by-step explanation:For example, the matrix A above is a 3 × 2 matrix. Matrices with a single row are called row vectors, and those with a single column are called column vectors. A matrix with the same number of rows and columns is called a square matrix.
Answer:
C
Step-by-step explanation:
This means that there is another leg of an isosceles triangle that is also 5 inches.
a^2 + b^2 = c^2
a = 5
b = 5
c = ?
c^2 = 5^2 + 5^2 Combine
c^2 = 25 + 25
c^2 = 50 Take the square root of both sides.
sqrt(c^2) = sqrt(50^2)
c = sqrt(5 * 5 * 2) Take out 1 of two factors under the root sign.
c = 5 * sqrt(2) The 2 is left over because there is only 1 of them
sqrt(2) = 1.4142
c = 5 * 1.4142
c = 7.07 = 7.1
