Calculate the value of x. Roundto nearest tenth A=29.7 B=6.3 C=0.2 D=14.5

1 answer:

3 0

B. 6.3 Because, for a triangle, you can use the angles to figure out the length. You can also tell that it can’t be D or A because it’s not longer than the base and it’s not small enough to be C.

Determine the factors of 3x2 + 10x − 8. (Which is the right answer?)

VMariaS [17]

ANSWER

$(3x - 2)(x + 4)$

EXPLANATION

The given quadratic trinomial is

$3 {x}^{2} + 10x - 8$

Comparing to the general quadratic trinomial:

$a{x}^{2} + bx + c$

We have a=1, b=10 and c=-8

$ac = 3 \times - 8 = - 24$

The factors of -24 that adds up to 10 are -2 and 12.

We split the middle term to obtain;

$3 {x}^{2} + 12x - 2x- 8$

Factor;

$3x(x+ 4) - 2(x + 4)$

Factor further;

$(3x - 2)(x + 4)$

The last option is correct.

What is the value of the expression 2 + 32 ⋅ (4 − 1)? A: 24 B: 29 C: 33 D: 37

Paul [167]

For this case we have the following expression:

$2 + 3 ^ 2 * (4 - 1)$

Rewriting the expression we have:

1) First we subtract the numbers within the parenthesis:

$2 + 3 ^ 2 * (3)$

2) Then, we solve the exponents:

$2 + 9 * (3)$

3) Then, multiplication:

$2 + 27$

4) Finally, the addition of numbers is made:

$29$

Answer:

the value of the expression is:

B: 29
