Answer:

the answer would be 5

Step-by-step explanation:

because if there was 15 truth or false questions that would be 45 points and if there where 5 essay questions that would be 55 questions 45+55=100 points and 15+5 questions is 20 questions so there would be 5 essay questions.

Find g(a-2)+3g(2a) if g(x)=x²-5x+8
sertanlavr [38]

Answer:

13a² - 39a + 46

Step-by-step explanation:

To find g(a-2)+3g(2a), find each part using the function g(x)=x²-5x+8.

g(a-2) = (a-2)²-5(a-2)+8 = a² - 4a + 4-5a + 10+8 = a² - 9a + 22

3g(2a) = 3{(2a)²-5(2a)+8} = 3{ 4a² - 10a + 8} = 12a² - 30a + 24

Combine the values to find g(a-2)+3g(2a).

g(a-2)+3g(2a) = (a² - 9a + 22) + (12a² - 30a + 24) = 13a² - 39a + 46

7. Given a right triangle as shown below, use a calculator to estimate the length of the
Wewaii [24]

Answer:

D. 11.6 cm

Step-by-step explanation:

The missing length of the right angled triangle can be calculated using Pythagorean Theorem as shown below:

c^2 - b^2 = a^2

Where,

a = x cm

b = 11 cm

c = 16 cm

Thus:

16^2 - 11^2 = x^2

256 - 121 = x^2

135 = x^2

\sqrt{135} = \sqrt{x^2}

\sqrt{135} = x

11.61895 = x

x = 11.6 cm (nearest tenth)
