Multiply. (3x - 2)(x + 5) A: 3x² + 17x - 7 B: 3x² + 17x - 10 C: 3x² + 13x - 10 D: 3x² + 6x - 7
Bess [88]

Answer:

The answer is C.

Step-by-step explanation:

You have to use Ditributive Law,

a(m + n) = am + an

So for this question :

(3x - 2)(x + 5)

= 3x(x) + 3x(5) - 2(x) - 2(5)

= 3 {x}^{2}  + 15x - 2x - 10

= 3 {x}^{2}   + 13x - 10

What is the measure of a°?
yuradex [85]

Answer:

<u>The correct answer is C. 129.</u>

Step-by-step explanation:

Let's recall that the Inscribed Quadrilateral Theorem states that a quadrilateral is inscribed in a circle if and only if the opposite angles are supplementary.

In the case of the inscribed quadrilateral ABCD in the graph attached, we have that:

m∠C= 51°, therefore its supplementary angle, ∠A, should be the difference between 180° and m∠C.

m∠C= 180° - m∠A

Replacing with the real values:

51 = 180 - m∠A

m∠A = 129°

<u>The correct answer is C. 129.</u>

spin [16.1K]
Turn 7/10 into decimal. (0.7)

Keep adding by 0.7 until you get the number closest to 4.1

3.5 is the closest, if we add another 0.7, we get 4.2.

So, he can get 5 sections of 0.7m
