Answer:

Option C : 7 +(-6) + (2+5)x

Step-by-step explanation:

Given :7 + 2(x – 3) + 5x

To Find :Which of the steps has an incorrect justification?

Solution :

$7 + 2(x -3) + 5x$

$7 + 2x -6+ 5x$

$7-6+2x+ 5x$

$1+7x$

So, Option C has an incorrect justification: 7 +(-6) + (2+5)x

Like terms can be added easily there is no need to apply distributive property .

Hence Option C has an incorrect justification

Answer:

54 sq units

Step-by-step explanation:

The triangle at the top (FAB) has a base of 10 and a height of 3. Area of triangle is 1/2bh so 1/2(10 * 3) = 1/2 * 30 = 15 sq units

If you cut off the triangle you have a trapezoid, EBCD. A trapezoid is (b1 + b2)/2 * h, so (6 + 7)/2 * 6 = 13/2 * 6 = 6.5 * 6 = 39 sq units

Add them together: 15 + 39 = 54 sq units

Which expression is equivalent to 6(3+0.05)?

Gnesinka [82]

$\huge{\boxed{6(3)+6(0.05)}}$

The distributive property shows that you need to multiply the $6$ separately by each term in the parentheses. This means you multiply $6*3$ and $6*0.05$ , then add them together to get $6*3+6*0.05$ , or in the terms of your answer choices, $\boxed{6(3)+6(0.05)}$ .
