Since the .16 is in the hundredths place, the fraction is 2 16/100, or 216/100

But if you need to simplify it it's 2 4/25, or 54/25

Alex_Xolod [135]

Answer:

Hence the expression $(a+b)(2a+3b)=2a^2+5ab+3b^2$

Step-by-step explanation:

Explanation

The given expression is (a + b)(2a+3 b).
We have to multiply the given expression.
Multiply the (a + b) by 3b, multiply the (a + b) by 2a then add like terms.

$\begin{matrix}{} & {} & {} & {} & a & + & b \\ \times & {} & {} & {} & 2a & + & 3b \\ \end{matrix}$

Can someone step by step explain the answer please

Vinvika [58]

Answer: z = $\sqrt{10}$

Step-by-step explanation:

To find z, you must set up a proportion to solve.

To find the altitude of a special right triangle, the formula is:

$\frac{a}{x} =\frac{x}{b}$

You can use 5 as a and 2 as b to complete the proportion:

$\frac{5}{z} =\frac{z}{2}$

Next, to solve:

Step 1: Cross-multiply.

$\frac{5}{z} =\frac{z}{2}$

(5)*(2) = z*z

10 = z²

Step 2: Take square root.

10 = z²

√10 = z

I hope this helps!
