Answer:

<h2>No</h2>

Step-by-step explanation:

Let's solve:

4(x + 2) + 3x + 7

Distribute 4 through the parentheses

= 4x + 8 + 3x + 7

Collect like terms

= 7x + 8 + 7

Add the numbers

= 7x + 15

Hope this helps..

best regards!

at one scholl at prep level there were 5 set of twins,two sets of triplets and one set of quadruplets starting school this year.
katen-ka-za [31]

Answer:  Fraction of twins = \frac{5}{8} Fractions of triplets = \frac{1}{4} Fractions of quadruplets = \frac{1}{8}

Step-by-step explanation:

Since we have given that

Number of set of twins = 5

Number of sets of triplets = 2

Number of sets of quadruplets = 1

Total number of sets is given by

5+2+1=8

Now, we need to find the fraction of those students.

So, Fraction of twins is given by

\frac{5}{8}

Fractions of triplets is given by

\frac{2}{8}=\frac{1}{4}

Fractions of quadruplets is given by

\frac{1}{8}

The area of a trapezoid is 864cm². It has a height of 24 cm, and the length of one of its bases is 30 cm. What is the length of
Amiraneli [1.4K]

The area <em>A</em> of a trapezoid with height <em>h</em> and bases <em>b</em>₁ and <em>b</em>₂ is equal to the average of the bases times the height:

<em>A</em> = (<em>b</em>₁ + <em>b</em>₂) <em>h</em> / 2

We're given <em>A</em> = 864, <em>h</em> = 24, and one of the bases has length 30, so

864 = (<em>b</em>₁ + 30) 24 / 2

864 = (<em>b</em>₁ + 30) 12

864 = (<em>b</em>₁ + 30) 12

72 = <em>b</em>₁ + 30

<em>b</em>₁ = 42
