To solve this, we must know the formula for surface area of a rectangular prism. The formula solves for 3 of the faces, and then multiplies by 2, because in a rectangular prism, 2 opposite sides will always be equal.

The formula is 2(wl+hl+hw)

Now all we have to do is substitute in our values and solve.

2(wl+hl+hw)=
2(12*11+11*11+11*12)=
2(385)=
770=

Using the math above, we can see that the correct answer is A. 770 square cm.

What is the coefficient of q in the sum of these two expressions? (23q – 34) and (–16q – r) NEED HELPPP

jeyben [28]

Answer:

The coefficient of $q$ is $7$

Step-by-step explanation:

The two expressions are

$23q-34$ and $-16q-r$ .

The sum of the two expressions is

$23q-34+-16q-r$

When we group like terms the expression will be,

$=23q-16q-r-34$

When we simplify the expression will now be

$=7q-r-34$

The coefficient of $q$ is the constant behind $q$ in the expression.

The coefficient of $q$ is therefore $7$ .

Evaluate 2(x+ 1 - 3 when x = 6 O Ο Α. 11 OB. 5 O C. 8 ( D. 10

Mashutka [201]

$\implies {\blue {\boxed {\boxed {\purple {\sf {A. \:11}}}}}}$

$\sf \bf {\boxed {\mathbb {STEP-BY-STEP\:\:EXPLANATION:}}}$

$2 \: ( \: x + 1 \: ) - 3$

Plugging in the value " $x\:=\:6$ " in the above expression, we have

$= 2 \: ( \: 6 + 1 \: ) - 3$

$= 2 \: ( \: 7 \: ) - 3$

$= 14 - 3$

$= 11$
