Hello,

h(x)=x²+1

k(x)=x-2

First of all, you must understand that:

(h+k)(x)=h(x)+k(x)

So, (h+k)(3)=h(3)+k(3)=(3²+1)+(3-2)=(9+1)+1=11

3h(2)+2k(3)=3*(2²+1)+2*(3-2)

=3*(4+1)+2*1

=15+2

=17

Answer 1-6 (about square root)

Taya2010 [7]

Answer:

1. For a cube, volume = $edge^{3}$

2. $\sqrt[3]{volume}$ = edge

3. Volume of the cube = 216 so, the edge = $\sqrt[3]{216}$ = 6

4. 1st blank = 6

2nd blank = 6

3rd blank = 216

4th blank = 216

5. 6 is the edge

6. As the room is a square and we have to find the side

Area = 121

Edge = $\sqrt[2]{121}$ = 11

If my answer helped, kindly mark me as the brainliest!!

Thank You!!

A smaller square is located inside a larger square. the length of the smaller square is 7 cm, and the length of the square is 12

patriot [66]

Let S=larger square side and s=smaller square side. The area between the larger and smaller is simple the larger area minus the smaller area. The area of any square being s^2. So our remaining area is:

A=S^2-s^2

A=144-49=95 cm^2

Gordon types 3,024 words in 42 minutes. Find the unit rate.

emmasim [6.3K]

Answer:

72 words per minute

Step-by-step explanation:

$\frac{1}{y}= \frac{42}{3024}$

42 × y = 1 × 3024

42y = 3024

42y ÷ 42 = 3024 ÷ 42

y = 72
