Answer:

I can help with Q "4" as -

It uses triangle congruence test - here we use - SAS, as

one side is equal as it is given

both the angles are 90 degree

and they share a same side

so -

8x = 6x + 5

8x - 6x = 5

2x = 5

x = 2.5

RU = 6x+ 5 = 6 (2.5) + 5 = 20

( I am not so sure but I think this is the answer )

Answer:

72 cupcakes

Step-by-step explanation:

Morgan can make 4 cupcakes with one cup of flour. She has 18 cups of flour and suppose she can make x cupcakes, then

1 cup of flour - 4 cupcakes

18 cups of flour - x cupcakes

Write a proportion:

$\dfrac{1}{18}=\dfrac{4}{x}$

Cross multiply:

$1\cdot x=18\cdot 4\\ \\x=72\ cupcakes$

What is the product?<br> (38b* )-822

sergey [27]

Answer:

$\boxed{\sf D)\:-24a^3b^7}$

Step-by-step explanation:

$\sf (3a^2b^4)(-8ab^3)$

We'll use rule of exponents to simplify expression.

$\sf 3^1a^2b^4(-8)^1a^1b^3$

Now, use the commutative property of multiplication.

$\sf 3^1(-8)^1a^2a^2b^4b^4$

In order to multiply power of the same base, we add their exponents.

$\sf 3^2(-8)^1a^{2+1}b^{4+3}$

→ Add exponents:

$\sf 3^1(-8)^1a^3b^7$

→ Multiply 3* -8

$\sf -24a^3b^7$
