Answer:

-5

Step-by-step explanation:

The dot means multiply:  so 3 \cdot 2 = 3 \times 2 = 6

Also:  5² = 5 x 5 = 25

Therefore,

-6-4(3 \cdot 2)+5^2

\implies -6-4(6)+25

\implies -6-(4 \times 6)+25

\implies -6-24+25

\implies -5

- 6 - 4(3 \times 2) +  {5}^{2}

*Note:- The dot represents the multiplication symbol

\to - 6 - 4 \times 6 +  {5}^{2}

\to - 6 - 4 \times 6 + 25

\to- 6 - 24 + 25

\to - 30 + 25

\boxed{ \sf \: ans =  - 5}

The answers to each of the given problems are;

1) Sum of two smallest integers  = 23

2) 3x + 6

3) 7.5 m/s²

<h3>How to find the sum of consecutive Integers?</h3>

1) We are told that sum of 4 consecutive integers is increased by 20 and equals 70. Thus, we have;

x + (x + 1) + (x + 2) + (x + 3) + 20 = 70

4x + 26 = 70

4x = 70 - 26

4x = 44

x = 44/4

x = 11

Thus, sum of two smallest integers = 11 + 11 + 1 = 23

2) Let the consecutive odd numbers be;

x, (x + 2) and (x + 4)

Sum of these consecutive odd numbers is;

x + x + 2 + x + 4 = 3x + 6

3) We are given the equation to find the acceleration as;

(v_final)² - (v_initial)² = 2ad

We are given;

v_final = 40 m/s

v_initial = 10 m/s

d = 100 m

Thus;

40² - 10² = 2a(100)

1500 = 200a

a = 1500/200

a = 7.5 m/s²

Choose the correct simplification of the expression (−2x + 8y)(9x − 3y).
Romashka-Z-Leto [24]
For these kinds of expressions use FOIL (first, outside, inside, last).

-2x • 9x = -18x^2
-2x • -3y = 6xy
8y • 9x = 72 xy
8y • -3y = -24y^2

Now combine them all:

-18x^2 + 78xy - 24y^2

Iteru [2.4K]

Answer:

£13496.80

Step-by-step explanation:

We can ignore the £ sign for now, that is just units.

If we decrease a number by 4.5%, we will have to find 100-4.5=95.5% of 14132.77.

We can easily do this by setting up a proportion.

\frac{x}{14132.77} = \frac{95.5}{100}

Multiply 14132.77 by 95.5:

14132.77\cdot95.5=1349679.535

Divide by 100:

1349679.535\div100=13496.79535

Rounding this to two decimal places, it simplifies to 13496.80.

Hope this helped!
