The answer is 76. multiply 15 times 4 which is 60.
and the triangle is the difference of the sides, so 19-15=4.
so then multiply the base and height, this leaves 4x4 which is 16.
then add the two. 60+ 16= 76

Which shows the expression below in simplified form? (2.4 × 1018) + (3.4 × 1015)

RUDIKE [14]

Answer: 5894.2

Step-by-step explanation:

You'll want to follow PEMDAS to simplify this expression.

1.) P - Parentheses

2.) E - Exponents

3.) M - Multiplication

4.) D - Division

5.) A - Addition

6.) S - Subtraction

We'll start with what's inside the parentheses:

(2.4 × 1018) + (3.4 × 1015)

(2,443.2) + (3,451)

Now all you have to do is add the values together to get your answer!

2,443.2 + 3,451

5894.2

Harry drove 2 hours on the freeway then decreased his speed by 20mph and drove 6 more hours. total trip was 352 what was his spe

poizon [28]

Recall your d = rt, distance = rate * time

we know the total trip was 352miles, so, let's say he was going for the first 2hrs at "r" speed, he went "d" miles, then he slowed down to "r - 20" and went 6 more hours, since the total trip is 352 miles, the 6hrs take the slack from 352 - d, and that's how many miles he covered on those 6hours

$\bf \begin{array}{lccclll}
&distance&rate&time\\
&-----&-----&-----\\
\textit{before slowing}&d&r&2\\
\textit{after slowing}&352-d&r-20&6
\end{array}
\\\\\\

\begin{cases}
\boxed{d}=2r\\
352-d=(r-20)6\\
----------\\
352-\boxed{2r}=(r-20)6
\end{cases}$

solve for "r".
