Answer:

Standard form of (x-9)(3x-7) + (3x^{2} - 5x+2) =6x^{2}  - 39x + 65

Step-by-step explanation:

Here, the given expression is (x-9)(3x-7) + (3x^{2} - 5x+2)

Now, simplifying the above expression in parts, we get

(x-9)(3x-7) = 3x^{2}  - 7x -27x + 63 = 3x^{2}  - 34x + 63

hence, combining both parts:

(x-9)(3x-7) + (3x^{2} - 5x+2)=(3x^{2}   -34x +63) + (3x^{2} - 5x+2)

= 6x^{2}  - 39x + 65

The above expression is of the STANDARD FORM: ax^{2}  +bx + c

Hence, the standard form of (x-9)(3x-7) + (3x^{2} - 5x+2) =6x^{2}  - 39x + 65

Answer:

#18)  <em>m</em>∠B = 107°

#19) <em>m</em>∠B = 17°

Step-by-step explanation:

*Supplementary angles are angles who's measures equal 180°

*Complementary angles are angles who's measures equal 90°

#18) If ∠A is 73°, then we must subtract 73 from 180.

180 - 73 = 107

This means that <em>m</em>∠B = 107°.

#19) If ∠A is 73°, then we must subtract 73 from 90.

90 - 73 = 17

This means that <em>m</em>∠B = 17°.

The ceilings in Roberto's house are 14 feet high. How many meters high are the ceilings? Do not round your answer.
monitta

Answer:

≈ 4.27 meters high

Step-by-step explanation:

Roberto's house is 14 feet high, we also know that 1 foot equals about 0.305 meters, so since we have 14 feet, we multiply 0.305 by 14 :

0.305 * 14

==> 4.27 meters

I’m stumped, can anyone please help me understand this
rodikova [14]

Answer:

<em><u>B. Store T sells apples at the lowest rate</u></em>

Step-by-step explanation:

Store R sells apples at $1.20 <u>per pound.</u>

Store S sells <u>4 pounds</u> of apples at $5.00.

Store T sells <u>3 pounds</u> of apples at $3.48.

To find the answer, <u>you have to find the unit price</u> for both Store S and Store T.

For Store S: 4 pounds = $5. <u>Divide the cost by the pounds</u>. This will give us <u>$1.25 per pound.</u>

For Store T: 3 pounds = $3.48. Same thing as Store S, d<u>ivide the cost by the number of pounds</u>. This will give us <u>1.16 per pound</u>.

Now, we know the unit prices for each store. It's time to answer the question.

A. Store R sells apples at the lowest rate.

This is <em><u>incorrect</u></em> because the store that sells the apples at the lowest rate is Store T.

B. Store T sells the apples at the lowest rate.

This answer is <em><u>correct</u></em>, but I'll also take a look at the other two

C. Store S charges a lower rate for apples than Store T.

Again, this is <em><u>incorrect</u></em> because Store T sells apples at the lowest rate.

D. Store T charges the same rate for apples as Store R.

<em><u>Nope</u></em>, Store T sells the apples at a lower rate than Store R.

This means your answer will be <u>B. Store T sells apples at the lowest rate</u>.
