Answer:
area = (1/2) · (p + q) · h
Step-by-step explanation:
1) 2m+6 / m² + 7m - 12 + (m+2)/(m+4)
= 2(m+3) / (m+4)(m+3) + (m+2)/(m+4)
= 2/(m+4) + (m+2)/(m+4)
= 2+m+2 / (m+4)
= m+4 / m+4
= 1 [ Option A ]
Answer 2) 3/ (x+4) + 7/ (x-3)
= 3(x-3) + 7(x+4)/ (x² +x - 12)
= 3x-9 + 7x + 28 / (x² +x - 12)
= 10x + 19 / (x² +x - 12) [ Option A ]
Hope this helps!
Answer:
? = 55
Step-by-step explanation:
if we put the triangles onto of each other
side CT is on top of TR
126 ÷ 70 = 1.8
70 × 1.8 = 126
BT is on top of TS
so,
99 ÷ ? = 1.8
99 = 1.8 × ?
99 ÷ 1.8 = ?
55 = ?
55 × 1.8 = 99
Hoped i helped :)
Ok don't panic!!!
First you look and see that 3 dozen is 36 and you need 720 cookies so that every person gets 2 cookies. so you first need to multiply 36 by 10 to get 360 then multiply that by 2.
So, in conclusion multipy each of the ingredients by 20! :)
17/16 x 20 = 340/16 of butter
5/8 x 20 = 100/8 of white sugar
7/4 x 20 = 140/4 of vanilla extract
15/8 x 20 = 300/8 of flour
5/6 x 20 = 100/6 of almonds
7/12 x 20 = 140/12 of confectioner's sugar
