Answer:

32 units squared

Step-by-step explanation:

Split up the figure into easy to find area parts. So, theres 2 triangles, and in the middle of those, you can make a square. And that would make the top part a large triangle! Now find the area of these

Large triangle: 1/2 (4)(10) = 20

Smallest triangle: 1/2(2)(2) = 2

Medium triangle: 1/2(6)(2) = 6

Square: 2*2 = 4

Now add them all up! 20+2+6+4 = 32 units squared!

The factors of 5y^2-2y-7 are (5y-7) and ???
gladu [14]
If we expand bx to jx and kx we have:

5y^2-2y-7

5y^2-7y+5y-7  then factor...

y(5y-7)+1(5y-7)

(y+1)(5y-7)

So the other factor is:

(y+1)

| Find the quadratic polynomial whose<br> Sum and products of zeros are 21/8 and 5/16
tatuchka [14]

Answer:

16x^{2} -42x+5

Step-by-step explanation:

Sum of its zeroes=\alpha +\beta =\frac{21}{8} \\

Product of its zeroes=\alpha \beta=\frac{5}{16}

Formula to form a quadratic polynomial:

p(x)=k[x^{2} -(\alpha +\beta )x+\alpha \beta ]

p(x)=k[x^{2} -(\frac{21}{8} )x+\frac{5}{16}]

p(x)=16[x^{2} -(\frac{21}{8} )x+\frac{5}{16}]

p(x)=[16x^{2} -42x+5]

The quadratic polyniomial is 16x^{2}-42x+5
