Answer:

29 units²

Step-by-step explanation:

You could divide this into two triangles and two trapezoids to find the area. But since the majority of these are either whole or half squares, I‘d count those. Then you’d just have one triangle in the top right corner.

Whole squares: 21

Half Squares: 10 (so 4 square units)

Triangle: 1/2(b)(h)=1/2(5)(2)=5

TOTAL = 21+4+5= 29 units²

One number is 7 more than another. If the sum of the two numbers is 165, find the two numbers.

timurjin [86]

x+7+x=165

2x+7=165

2x+7-7=165-7

2x=158

2x÷2=158÷2

x=79

79+7+79=165

Step-by-Step Solutions begin on pag phing. 2. y=x² - 4 y = -3

rusak2 [61]

<h3>The solution is (1, -3) or (-1, -3)</h3>

Solution:

Given that,

$y = x^2 - 4 ------- eqn\ 1\\\\y = -3 ---------- eqn\ 2$

We have to find the solution (x, y)

Substitute eqn 2 in eqn 1

$-3 = x^2 - 4$

$x^2 = -3 + 4\\\\x^2 = 1\\\\Take\ square\ root\ on\ both\ sides\\\\x = \pm 1$

Thus, we get,

x = 1

x = -1

Thus the solution is (1, -3) or (-1, -3)

Find the slope of the line that passes through (4, 6) and (1, 10).

Jlenok [28]

Answer:

given us,

(x1y1) = (4,6)

(x2y2)= (1,10)

here

slope= (y2-y1)/ (x2-x1)

= (10-6)/ (1-4)

= 4/ (-3)

Step-by-step explanation:

4/ (-3)

Need help!!! solve for p) n = (p-k) ------ j Sorry for the terrible fraction

almond37 [142]

Answer:

nj +k = p

Step-by-step explanation:

n = (p-k)/j

Multiply each side by j

nj = (p-k)/j *j

nj = p-k

Add k to each side

nj +k p-k+k

nj +k = p
