PLEASE HELP ME<br> Which expression is equivalent to –8(–5k+4)+6k

zheka24 [161]

Answer:

the last option (-5k+4)-8 + 6k

Step-by-step explanation:

-8(-5k+4)+6k

to simplify, begin by distributing the -8 so that parentheses are removed:

=(-8)(-5k) + (-8)(4) + 6k

=40k - 32 + 6k

combine 'like terms':

46k-32

the only answer which simplifies to 46k-32 is the last option:

the only difference between the original problem and the last option is that the -8 value is behind the parentheses instead of in front of it; it simplifies to be 46k-32

Q6 Q19.) Write the expression as the sine, cosine, or tangent of an angle. Then find the exact value of the expression.

Greeley [361]

Using sin(A+B) = sinAcosB + cosAsinB

sin20cos40 + cos20sin40 = sin(20+40) = sin60degree

= $\frac{ \sqrt{3}}{ 2}$

The grocery store is having a sale on frozen vegetables. 4 bags are being sold for $5. At this rate, what is the cost of 7 bags?

Brums [2.3K]

Answer:

$8.75

Step-by-step explanation:

Create a proportion where x is the cost for 7 bags:

$\frac{4}{5}$ = $\frac{7}{x}$

Cross multiply and solve for x:

4x = 35

x = 8.75

So, the cost of 7 bags is $8.75
