just olya [345]

Answer:

Step-by-step explanation:

To distribute means to multiply everything outside the parenthesis with everything inside the parenthesis, so in this case 7x8 then 7(x) then 7x2 so that is equal to 56 + 7x + 14, so combine the 56+14 so we get 7x + 70.  I hope '7' is part of the problem and not the question number

Ok so i know how to multiply in scientific notation but this one is so hard. pls help and PLS show your work.
juin [17]
Basically if you have an exponent at the end of a 10, 10^{7} , then in the end the extended notation is going to have 7 zeros. So it'll be 10000000. Then you multiply whats in the rest of the equation together. There's the beginning :) I hope it helps.

Find the area of the shaded portion the one who answer first will get brainliest
slega [8]

Answer:

≈ 77 cm²

Step-by-step explanation:

The area of the shaded portion is calculated as

area of outer sector - area of inner sector

= (πR² - π r²) × \frac{60}{360} ( R is the outer radius, r is the inner radius )

= (π × 14² - π × 7² ) × \frac{1}{6}

= (196π - 49π ) ÷ 6

= 147π ÷ 6

≈ 77 cm² ( nearest whole number )

Find the length of UV. v(2,-1) u(1,-9)
fiasKO [112]

Answer: \sqrt{65}

Step-by-step explanation:

<u>Concept:</u>

Here, we need to know the concept of the distance formula.

The distance formula is the formula, which is used to find the distance between any two points.

If you are still confused, please refer to the attachment below for a clear version of the formula.

<u>Solve:</u>

Find the length of UV, where:

  • U (1, -9)
  • V (2, -1)

Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Distance = \sqrt{(1-2)^2+(-9+1)^2}

Distance = \sqrt{(-1)^2+(-8)^2}

Distance = \sqrt{1+64}

Distance = \sqrt{65}

Hope this helps!! :)
