What is the value of expression below when c = 5 and d=4 6c²-5d + 8
Alisiya [41]

Answer:138

Step-by-step explanation:

First plug in the c and d values into the expression:

6(5)^2-5(4)+8

Remember PEMDAS, so you do 5^2 first getting you 25.

6(25)-5(4)+8

Continue with PEMDAS and multiply -5 and 4, and that gets you -20.

150-20+8

Now you simplify the expression to get: 138.

Katia and Thomasina play a computer game and record these scores. Katia: 8, 6, -4, -7, 2, 0, 3 Thomasina: -11, 0, 8, 7, 5, -7, 1
suter [353]

Answer:

Step-by-step explanation:

there is no factorization of y^2 -2y +35 in real numbers

Thomasina correctly determined two factors of 35 that differ by 2, but that is not what is needed here. For this problem, she needs two factors of 35 that have a sum of 2.* (There aren't any real-number factors that meet that condition.)

__

The factorization in complex numbers would be ...

 = (y -1 -i√34)(y -1 +i√34)

_____

* Technically, she needs two factors of 35 with a sum of -2. Both factors would have to be negative.

The simplest form of the expression 4m-17/m^2-16 + 3m-11/m^2-16 has ____in the numerator and___ in the denominator.
lara31 [8.8K]
For this case we have the following expression:
 \frac{4m-17}{m^2-16} + \frac{3m-11}{m^2-16}
 Since the denominator is equal, then we can add the numerator.
 We have then:
 \frac{(4m-17) + (3m-11)}{m^2-16}
 Adding similar terms we have:
 \frac{(4m+3m) + (-17-11)}{m^2-16}
 Rewriting we have:
 \frac{7m - 28}{m^2-16}
 Doing common factor in the numerator we have:
 \frac{7(m - 4)}{m^2-16}
 Factoring the denominator we have:
 \frac{7(m - 4)}{(m-4)(m+4)}
 Canceling similar terms we have:
 \frac{7}{m+4}
 Answer:
 
The simplest form of the expression has 7 in the numerator and m+4 in the denominator.
