Answer:

4 t^2 + 6 t + 2

Step-by-step explanation:

h(t)=2t+1 and g(t)=2t+2

(g•h)(t) = (2t+1) (2t+2)

FOIL

first: 2t*2t = 4t^2

inner : 2t*1 =2t

outer: 2t*2 =4t

Last : 2*1 =2

Add them together

4 t^2 + 2 t+4t + 2

4 t^2 + 6 t + 2

The answer would be (2t+1)(2t+2) which is equal to 4t^2 +6t +2

Eight less than a number is six more than twice the same number.<br> I need the number.

mariarad [96]

The answer is -14

Explanation:

x - 8 = 2x + 6

We move all term to the left

x - 8 - ( 2x + 6 ) = 0

We get rid of parentheses

x - 2x - 6 - 8 = 0

We add all the numbers together, and all the variables

-1x - 14 = 0

We move all terms containing x to the left, all other term to the right

-x = 14
x = 14/-1
x = -14

Find the area pls- i need help

Tresset [83]

Answer:

1. 36 sq un

2. 40 sq un

3. 20 sq un

Step-by-step explanation:

The answer for number one is 36 square units because the rectangular area is 24 sq un and the triangular area is 12 sq un so I added them to get 36 sq un. The second answer is 40 sq un because if you cut the shape into 2 shapes you get 2 equal trapezoids. Each trapezoid is 20 sq un so I multiplied it by two to get 40 sq un. The third answer is 20 because the side triangles are 2 sq un each and the square on the bottom is 16 sq un. By the way, sq un means square units lol.

Find the missing probability. P(A)=7/20,P(A∪B)=191/400,P(A∩B)=49/400 ,P(B)=? A. 7/8 B. 1/4 C. 117/400 D. 19/40

spin [16.1K]

Answer:

Step-by-step explanation:

P(AUB)=P(A)+P(B)-P(A∩B)

191/400=7/20+P(B)-49/400

P(B)=191/400+49/400-7/20=240/400-7/20=12/20-7/20=5/20=1/4
